For the hair dye to work you need to either use bleaching before blue dye, or use a dye that includes a lot of bleaching (which usually works less well).
For a video pretty much talking about how stupid people can be he should have known that (and I'm sure he did)... No sane person would believe you could dye black hair straight away...
@@snig88 he's probably never worked with or had to worry about hair dye before considering how much he didn't want to lose his black hair so I don't blame him tbh but it was kind of silly
The screenshot one when you change your rubbish circle to a perfect one, works with other shapes too (squares, triangles etc), but gets confused a bit when you go beyond a five-sided shape. Not sure how useful it actually is in day-to-day life but neat nonetheless!
Its would work trust me we teach that here in Belgium also the experiment the candle experiment worked because the oxygen in the bottle have been absorbed by the fire , so basically the water takes the percentage of the oxygen that was in the bottle
8:08 That is very, VERY dangerous. The only thing keeping the heating elements from melting and catching fire is the flow of cool air. If your hair dryer is old and doesn't have a safety system, it can burn down your house.
I doubt anyone has a hair dryer without that safety system. It is illegal for them to be produced without them and this has been the standard for decades. It's necessary because hair dryers will shut down even when using them normally for too long, which is something I've had to deal with that issue when using them in projects to speed up something drying. The closer you hold the hair dryer to the thing you're trying to dry, the faster it will overheat and shut down. The reason is that air has to flow from one end to another. The effect is the same whether you block it from the front or block it from the back.
8:18 the hairdryer was sparking because it needs the airflow to cool down the heating element and prevent it from melting, restricting that airflow resulted in that heating element melting and since the heating element is also resistor limiting current to the motor in the hair dryer it stopped working completly.
This is what sets Arun apart from the rest of the crowd. He doesn't just do a thing and shows it working or not working. He explains why it works or if something doesn't work, explains why it doesn't or how it has potential to work if done a bit different. Top notch content.
8:15 - the hairdryer isn't broken, it's just a fail safe that shuts down the dryer if its airflow is poor or it gets too hot. The spark is normal when safety engages, leave it for a few minutes and it will work again.
9:07 Correcting a few stuff here. First of all having the inside hotter would only make the pressure inside higher. Secondly, that happens because fire needs oxygen to continuously burn as the oxygen use up the pressure decreases, pulling in the water around it to about 20% of he volume since that's how much oxygen in the bottle and atmosphere.
He didn't know that people with knowledge of what is happening are here.. He completely made up all science explanations ... Ig that's why he's a UA-camr 😅😅😅
@@Summer-gw9xf CO2 is also more dense than O2 which will also free up space in the bottle for water (and the water from the reaction will also help). You also see that water is already being sucked up before the flame dies
@@Tommienio the CO2 produced won't change volume by much cause carbon in in solid form and it will be added to O2 .CO2 and O2 occupies same amount of space causing CO2 to be more denser which doesn't result in water rising. The reason for water rising is due to paraffin binging burnt. Paraffin in carbohydrates like higher form of CnHm. And reaction is like CnHm + O2 --> CO2 + H2O. Resulting in more water formation. And if u let it cool after the O2 is used the volume of air decreases, increasing the water level again.
You science people up there, shut the fuk up... we here for some entertainment stuff not for for your science lesson... go to universities, leave us. Jezzz
About the battery light bulb one: In the first clip, they connected positive terminals of the batteries to both positive and negative terminal of the light bulb, which means, there's no way for electricity to flow. In the 2nd clip, they've connected the terminals right(except for the 2 positive terminals touching together, that doesn't do anything in this case), but there's still no closed circuit, They'd have to connect the free terminals together to close the circuit (and turn the bottom battery around, so the positive terminal touches the negative terminal). So basically just running the batteries in serial connection to increase voltage to a higher amount. I've made a light bulb run on 60V from serially connected 9V batteries.
@@Tommienio depends on the bulb in these modern times. A normal incandescent bulb will work with either AC or DC as it is just electricity going through a filament and it doesn't matter if the electricity is alternating or not. An LED bulb on the other hand is designed to be used with AC and probably won't work with DC.
The marker trick is kinda true. Yellow and green highlighters are very visible under blue filtered light (much more so than in regular light) which stage technicians use to for example make notes behind the stage where we can only have a little bit of blue light. Yellow light would often be visible to the audience. It's a bit different between different highlighters though how well you can see them, and I have never tried diluting one...
The spark inside the hair dryer was the thermal switch stopping the whole case from melting because of restricted airflow. It should come back on in a few minutes
@@shno_deela6986 they certainly can be, the only reason I've ever seen one spark before was when the brushes were going out and I just figured the odds of that on his hair dryer were pretty slim but I guess, in reference to what that other person mentioned, maybe the restricted air flow would be a factor...? I'm sorry but I really don't think the sparks were edited in, that is just pointless.
9:23 I knew about this one. I worked at Starbucks for about 6 years. We used to steam the milk jugs with our steam wand so that we could crunch them up quickly and make more room in our recycling bin. It’s astonishing how small they can get 😂
Technically speaking, a high enough voltage potential would cause the air to ionise and close the circuit, but that would be in the 100s of kVs and also destroy the bulb, not to mention needing not batteries but a proper high voltage power supply , but you're spot on with the explanation
Someone had to say it... The reason at 7:09 isn't completely correct... as the 1.5V potential difference has nothing to do with the trick not working... It's simply because the circuit is actually open.. so no actual current flows through the lamp. :)
The thing about coloring your hair is you need it to be bleached blonde, in order for the color to pop out. It's like adding blue to a black can of paint it's never gonna work. And for the color to pop out more you need to be really blond, like Targaryen white hair blond.
You were somewhat right with the bottle and candle one. The flame from the candle is also burning up all the oxygen inside of the bottle creating a vacuum, which then sucks the water up into the bottle.
7:11 This reason for why it doesn't work is not wrong, but it's definitely not the main one. The circuit is just not completed, so there is no electricity flowing. To complete it you'd need to connect the negative poles of the batteries to the light bulb as well.
9:05 I think that happens not because the heat decreases the air pressure, its because the fire while burning uses up the oxygen hence decreasing the air pressure. (in fact, heat would INCREASE the air pressure because it makes the air inside expand)
YOU ARE ACTUALLY THE BEST TECH CHANNEL! Keep up the engaging and entertaining content! How did you make the part at 2:26 where the fried egg flies off screen like a "Star Wars Plane"?
9:00 heatin up a gas would actually expand it (PV=nRT) but what's happening is that for every 2moles of oxygen used up only 1mole of CO2 is produced (and 2moles of H2O) resulting in half as much gas in addition to when this hot air cools down after the candle blows out from the lack of O2 that the pressure drops even further and sucks up water
6:23 well it has noting to do with the atmospheric pressure as it doesn't depends on the surface area. The real concept behind it is the viscose force or the air drag with depends on the area. 7:13 it doesn't work because the circuit is not closed in the first place. Even if we use 220V ac and connects its one terminal, it still wont work
I haven't actually tried it, but at 7:01 they put the 2 plus sides together and the minus side of the battery is facing the bottom of the lightbulb whereas you did the opposite
6:10 it was actually in our 6th or 7th standard textbook.. if you flat out the paper on the ruler, there is little air below the paper but much on the upper side, so the air pressures the paper down.. paper increases the area of air pressure.. so pressure × area = more force
8:03 the reason it failed was because you jammed the fan, you're not supposed to use 99%+ airtight matter, use something like a thin piece of paper, or a sock
7:09 for the bulb to light you need to complete the circuit. even you have batteries totaling 230v, the bulb will still not light without a complete circuit.
@@pratishthabajracharya7 It needs one end of the circuit connected to the bottom pointy part and the other end connected to the side of the part screws into the outlet. So you would need a wire connecting the bottom batteries to one of the side batteries.
@@leonkolaric5158 it would still work. That is a led bulb it seems and they rectify the 230V ac and turns it into DC internally anyways. And if it is a incadecent bulb it doesn't matter, they light up anyways
Oh man that butter trick is hilarious. Really surprised that actually works as well as it does. Definitely gotta try that next time I'm hammered at the local diner eating pancakes at 3am. I feel that scenario is what that trick was destined for lmao.
9:09 what you said is partially true but it's actually because as the air in the bottle gets hotter the air expands (as atoms are energized with rise in temp) and so the volume in there increases, so the hot air molecules escape the bottle by leaving through the water creating bubbles and the water fills the bottle due to the atmospheric pressure created so the candle floats wow felt like a nerd typing this
Sorry, I’m about to be even more of a nerd. UM ACTUALLY 🤓 First of all, the air does expand, but its volume doesn’t increase; the bottle is rigid and therefore its volume is fixed. As a result, it’s the pressure of the air inside the bottle that increases. However, the water entering the bottle has nothing to do with the increase in air pressure or the air leaving the bottle (which it doesn’t; the only increase in pressure is a result of the air being heated). It’s actually quite the opposite. As the area inside the bottle is air tight, no fresh oxygen can come through for the candle to keep burning. So as the candle burns, it depletes the oxygen portion of the air in the bottle, which makes up a significant amount of the initial air pressure inside, which means the air pressure will decrease. Now that the air pressure inside the bottle is less than outside the bottle due to the reduced number of gaseous molecules, the water starts coming in to equalize the pressure. It’s likely this process is also partially caused by the cooling of the air in the bottle when the candle stops burning, which also decreases the pressure. I am aware that was completely unnecessary, I’m sorry.
11:26 fun fact, no. Alcohol does not burn off that easily. In fact, a lot of alcohol stays in dishes, even in many long cooked ones a little alcohol still remains and doesn't burn off magically. Adam Ragusea made a great video on this, you should watch it.
I guess in this case its alright to use a metal knife, since that particular toaster does not use traditional heating coils/plates but instead uses steam/moisture to toast the bread
3:48 I just thought of a way to use this to listen to music, and change the song without touching your phone, like when your in the shower Basically make it to where when you say like next song or next video etc, it presses the next video button
5:15 it’s the same with iPad’s pencil. For eg in the notes app if you want to create a straight line, just draw a line and hold. It will correct. You can do the same with a circle, a star, arrow and many more
You know what I love about this video It's the fact that they take the time to actually go in to depth with some things like further explain instead of just checking the hack and getting it over with
Your my favorite youtuber!!!! You taught me so much about tech!!! I'll be looking out for your next video. You get a five-star rating!!! I've seen every one of your videos!!!
5:04 This feature isn’t confined to screenshots; it’s system-wide. Works in Notes too. Also other shapes: triangles, squares, arrows, curves, ovals, etc.
1:48 you can actually create a variety of symbols beyond just the apple logo. If you hold down option + shift + any other key on your keyboard (basically) I believe you get a bunch of other characters! I'm not really sure because I use a windows and haven't used a mac in a while, but it should still work!
@@mr.m.2701 It works for me, are you sure you are holding option + shift + K at the same time? On some places I don't think it works so maybe try somewhere else.
@@Eraser.r Yes, the buttons are holding at the same time. Both sides of the keyboard were tested. I only get these ˆ symbol when I pressing the keys. I have German Layout, maybe that's the reason.
12:31 thats not real but it works on some claw machines but on every claw machine there’s a secret settings in the back to change the amount of weight it can hold so for example a key chain claw machine they put the settings on low because there light but if its a big toy it has to be on high but some arcades put big toys and on low settings to scam you. Hope that helped 😊
8:08 The hair dryer actually sparks because there are heating coils inside it which get hot when electricity is passed through, But turning on the electricity also starts the back fan which pulls cooler air in from the back ultimately cooling the coils just enough for it to not break or melt but when you cover the back side with a mask it resists the air flow in, triggering this weird mechanism which turns off the hair dryer for some time, Then starts working normally. I suppose it does this so it doesn’t get permanently damaged. That was kinda long...
For the candle TikTok, we did a similar experiment in science class. It was boiling water in a 12oz can(small amount) making the can fill with steam replacing the cool oxygen. Then we dunked the van into cold water(opening first) which makes the water vapor holding up the can condense therefore making the can collapse on itself and crush. It was really cool but I had to wait like 15 min for the water to start steaming on a hot plate
Quick clarification: For the candle trick, the reason the water actually flows inside is because the oxygen on the inside of the bottle is used up, thus reducing the air Pressure!

For the light bulb trick at 7:10, even if the voltage was right it wouldn't turn on because the circuit is not closed. It's basically an open breaker
Also there are low voltage light bulbs available like those in old flashlights. They can be powered with 3V. Still, great content ;)

6:23 well it has noting to do with the atmospheric pressure as it doesn't depends on the surface area. The real concept behind it is the viscose force or the air drag with depends on the area.
7:13 it doesn't work because the circuit is not closed in the first place. Even if we use 220V ac and connects its one terminal, it still wont work
I haven't actually tried it, but at 7:01 they put the 2 plus sides together and the minus side of the battery is facing the bottom of the lightbulb whereas you did the opposite
It doesn't matter here. Cuz either way, the circuit isn't a closed one.
11:22 his home is like a palace
Don't fall for days cam
6:10 it was actually in our 6th or 7th standard textbook.. if you flat out the paper on the ruler, there is little air below the paper but much on the upper side, so the air pressures the paper down.. paper increases the area of air pressure.. so pressure × area = more force
Congrats on 16 million!
13:05 bro man looks like the nerd from minons LOL
YOU JUST GOT VECTORED
@@Q9wihsioa 🤣🤣🤣🤣
he is the nerd from minons!!!!
Lol the "rub hair dye into hair that is darker than the color you're dyeing it and hope it works" should be another hack fail on the list 😂
8:03 the reason it failed was because you jammed the fan, you're not supposed to use 99%+ airtight matter, use something like a thin piece of paper, or a sock
But the TikTok said use a mask
@@amandaandneesa7126 but your mum told you to shut up
I think they test beforehand to make sure it's almost exactly half but one over so he gets the hair and the viewer gets the reward for staying tuned
7:09 for the bulb to light you need to complete the circuit. even you have batteries totaling 230v, the bulb will still not light without a complete circuit.
can you tell me what other parts it needs to become a complete circuit?
and it still would not light because the bulb needs AC current and batteries are DC
@@pratishthabajracharya7 You need negative/positive on one side, and the opposite on the other
@@pratishthabajracharya7 It needs one end of the circuit connected to the bottom pointy part and the other end connected to the side of the part screws into the outlet. So you would need a wire connecting the bottom batteries to one of the side batteries.
@@leonkolaric5158 it would still work. That is a led bulb it seems and they rectify the 230V ac and turns it into DC internally anyways. And if it is a incadecent bulb it doesn't matter, they light up anyways
Oh man that butter trick is hilarious. Really surprised that actually works as well as it does. Definitely gotta try that next time I'm hammered at the local diner eating pancakes at 3am. I feel that scenario is what that trick was destined for lmao.
9:09 what you said is partially true but it's actually because as the air in the bottle gets hotter the air expands (as atoms are energized with rise in temp) and so the volume in there increases, so the hot air molecules escape the bottle by leaving through the water creating bubbles and the water fills the bottle due to the atmospheric pressure created so the candle floats
wow felt like a nerd typing this
Sorry, I’m about to be even more of a nerd.
UM ACTUALLY 🤓
First of all, the air does expand, but its volume doesn’t increase; the bottle is rigid and therefore its volume is fixed. As a result, it’s the pressure of the air inside the bottle that increases. However, the water entering the bottle has nothing to do with the increase in air pressure or the air leaving the bottle (which it doesn’t; the only increase in pressure is a result of the air being heated). It’s actually quite the opposite. As the area inside the bottle is air tight, no fresh oxygen can come through for the candle to keep burning. So as the candle burns, it depletes the oxygen portion of the air in the bottle, which makes up a significant amount of the initial air pressure inside, which means the air pressure will decrease. Now that the air pressure inside the bottle is less than outside the bottle due to the reduced number of gaseous molecules, the water starts coming in to equalize the pressure. It’s likely this process is also partially caused by the cooling of the air in the bottle when the candle stops burning, which also decreases the pressure.
I am aware that was completely unnecessary, I’m sorry.
Why you straining yourself
@@THE__BLUE That's a great question. If only I knew the answer.
Not true, it's that the oxygen goes away and the water comes to replace it
Du bist der beste UA-cam für einschlafen
11:26 fun fact, no. Alcohol does not burn off that easily. In fact, a lot of alcohol stays in dishes, even in many long cooked ones a little alcohol still remains and doesn't burn off magically. Adam Ragusea made a great video on this, you should watch it.
10:09 Arron putting a metal knife in a toaster 😵💫
I guess in this case its alright to use a metal knife, since that particular toaster does not use traditional heating coils/plates but instead uses steam/moisture to toast the bread
Yeah arron
..........
Omg
Arun my man, Arun.
Correction: Arun

I just thought of a way to use this to listen to music, and change the song without touching your phone, like when your in the shower
Basically make it to where when you say like next song or next video etc, it presses the next video button
These life hacks are both hilarious and surprisingly helpful sometimes.
5:15 it’s the same with iPad’s pencil. For eg in the notes app if you want to create a straight line, just draw a line and hold. It will correct. You can do the same with a circle, a star, arrow and many more
You know what I love about this video
It's the fact that they take the time to actually go in to depth with some things like further explain instead of just checking the hack and getting it over with
Your my favorite youtuber!!!! You taught me so much about tech!!! I'll be looking out for your next video. You get a five-star rating!!! I've seen every one of your videos!!!
incredible video, thanks for going in-depth!
5:04 This feature isn’t confined to screenshots; it’s system-wide. Works in Notes too.
Also other shapes: triangles, squares, arrows, curves, ovals, etc.
thanks i use notes alot
1:48 you can actually create a variety of symbols beyond just the apple logo. If you hold down option + shift + any other key on your keyboard (basically) I believe you get a bunch of other characters! I'm not really sure because I use a windows and haven't used a mac in a while, but it should still work!
Yeah, a lot of symbols but no apple logo. :) I typed my keyboard up and down and no apple logo. it would be cool if its working.
@@mr.m.2701 It works for me, are you sure you are holding option + shift + K at the same time? On some places I don't think it works so maybe try somewhere else.
@@Eraser.r Yes, the buttons are holding at the same time. Both sides of the keyboard were tested. I only get these ˆ symbol when I pressing the keys. I have German Layout, maybe that's the reason.
@@mr.m.2701 if you have a different language it most likely won't work.
This guy will risk his entire house to show us how dumb TikTok trains can be. Honestly I got a respect it.
Guy is now a tech doctor with that awesome lab court 👏
12:31 thats not real but it works on some claw machines but on every claw machine there’s a secret settings in the back to change the amount of weight it can hold so for example a key chain claw machine they put the settings on low because there light but if its a big toy it has to be on high but some arcades put big toys and on low settings to scam you. Hope that helped 😊
I love how he's educational but also really funny
" Hahaa! It's A s CD Bubble!!.... oh dear god..." That was the funniest Thing i've seen all Day!! - Thank You Arun!
Fun fact :the combination at 12:25 is literally the konami code💀
He never fails to rickroll us in the most unexpected ways possible on a side note you videos are trully amazing big fan
where is the rickroll in this video
@@BeatBassMusic i was wondering the same
wait I missed it in this video, do you have a timestamp?
oh, no sorry it was a joke ,sory
Good editing 2:28
i like your editing
:)
Thankyou Arun for teaching us . Everything in technology . ❤️❤️❤️❤️❤️❤️ I leaned a lot of thing from this video ✨✨✨
Rare moment when I m here in 10 seconds
Lol. I was here in 36 seconds
@Bruh Bruh bot
Even I was here in 10 seconds…
Before I refreshed.
4 min here 😅
7minutes
8:08 The hair dryer actually sparks because there are heating coils inside it which get hot when electricity is passed through, But turning on the electricity also starts the back fan which pulls cooler air in from the back ultimately cooling the coils just enough for it to not break or melt but when you cover the back side with a mask it resists the air flow in, triggering this weird mechanism which turns off the hair dryer for some time, Then starts working normally. I suppose it does this so it doesn’t get permanently damaged.
That was kinda long...
Basically a failsafe
thank you for testing all tiktok lifehacks it must've took you a lot of time ❤
The fact Arun just puts a metal butter knife in a plugged toaster oven 💀😭
Just love the reaction change from 13:26 to 13:28🤣
Thank you, Arun, for such enjoyable content!
For the candle TikTok, we did a similar experiment in science class. It was boiling water in a 12oz can(small amount) making the can fill with steam replacing the cool oxygen. Then we dunked the van into cold water(opening first) which makes the water vapor holding up the can condense therefore making the can collapse on itself and crush. It was really cool but I had to wait like 15 min for the water to start steaming on a hot plate
