I did say "bare" on the first one, and although that is tricky, I originally thought it was fair. I will add text that says "bare copper wire" when I post these as shorts. People have been wanting them to be more difficult, so I was trying to make it tough and it felt like taking too much time to point that out would give it away. In hindsight though, it appears most people didn't notice that I even said that at all so that's my bad.
Thank you. These really were more difficult.
Usually (90% of the time) I know the answer, but in this episode I could only eliminate one option per set.
I think that trick questions don't fit the show, as it is science-related. If something is similar to the real experiment, it should be clear, what is actually checked, like it was with bubbles, where the direction was clearly important. Harder questions should rely on more obscure facts, not on tricks.
Thank you! You could have been a bit clearer about that, but we should have noticed it when we saw the bare copper wire... Without the bare thingy for many the guess would have been too obvious.
I highly suspected that lightning has to travel in reverse to equalize if the positively charged side is on the other side. So I was so sure that B (rock candy) had to be fake. 😂
@@vladko312 i'd argue that it does teach something science related - that electromagnets are formed from coils and not just solid masses of metal.
hi im iranain its not candi its a nabat
The first one was cheating! Most transformer coils have a transparent insulation layer
Yes, lacquer insulated copper wire is very common for making coils. At sight it could be very hard to distinguish from a plain copper wire.
But he did say "bare" copper wire.
@@thedino2712 ah, I missed that.
@@thedino2712 Even bare wire could have a thin layer of dirt, fat, oxidized copper, etc. that restricts current enough to act as an insulator.
As an electrical engineer, I fell for that trap, too. People call it copper wire, but lacquered copper wire is extremely common. Also, the bolt could have been aluminum, which would have made it an extremely weak magnet.
He could have also used an advanced battery that checks for a load. If there isn't enough resistance in the system, it won't close the circuit. Of all the ways to trick an electrician, it was the simplest. 😂
he did say BARE copper wire, it's a fair cop. I didn't notice that, and so you got me.
Same
Remember kids, rusting is the same thing as fire, just WAY slower.
Depends what you mean...
If you mean it is a process where some reductant is oxidized by oxygen, then yes, that is also true for fire, but rusting certainly is not a form of combustion, which is what is usually considered "fire".
@@HenrikMyrhaug yes, I meant that they are both exothermic oxidation reactions, so the result of letting steel wool rust is the same as setting it on fire, both in terms of the state of the iron and the total amount of heat released. The heat is just released faster.
just WAY cooler
As burning, not as fire. Minor detail but still
@@AloisMahdalI wonder how the total heat energy released compares
I got trolled by the bare copper, didn't notice that detail. Figured it was weird that there was no "all are correct" options on this video LOL
Steel wool wasn't too difficult and I thought of surface tension for the straw, yipee 🥳
Your short-form videos have pavlovianlly trained me to examine carefully every video on the internet, I always ask myself, "Does this make sense? How easy would it be to fake it?" Thank you very much
HOLY CRAP, YOUR SUBSCRIBER COUNT HAS SKYROCKETED SINCE I LAST CHECKED!!! CONGRATS!!!!!
yet it's still 0,0001 % of what i wish it was
I can't tell what's real anymore, this series has made me lose my sense of reality 😥
This justifies me never touching grass: fear of being struck by lightning
it takes the path of least resistance so if there's anything taller than you touching the ground it'll go through that
this is why i only hang out w people taller than me. aint no way i'm gonna let god smite me in particular
@@janthran What if you have lower resistance?
@@MegaTechno just say no - lightning can’t strike you without your consent
How does the polarized one work? It makes no sense that blocking even more light would somehow make it visible.
I wish he had explained this, but I looked it up, and it comes out of applying Malus’ Law. The order of the polarizers is important here.
The third filter allows SOME light to pass through. It has to do with how the light particles are channeled through from your point of view. With the other two filters, some light is blocked that is 'beamed' one way or the other. Both filters catch almost all of the light particles going towards your eyes as they go through the filters. The third filter allows some light from one filter, and some light from the other filter, but not all.
I came here to ask this, and after reading these responses, thank you but I'm afraid I still don't understand... 😅
@@garthvader9916 it’s because polarizers don’t just block light they also change the angle. If you have two polarizers at any angle that is not 90 degrees some light will get through and the angle of that light will be in line with the second polarizer. If you add a third polarizer it will only block all light if it is at a 90 degree angle from the second polarizer.
Since the explanations here are somewhat unclear, let me explain as someone with a physics degree who has used polarizers.
Light waves have an angle, called an orientation, which is perpendicular to the direction the light is traveling. Normally light from a source like a light bulb has a bunch of random orientations. Polarized light all has a single orientation.
A polarizer makes light polarized in the direction of the polarizer, but it does that in a very particular way. Light oriented perpendicular to the polarizer direction is blocked entirely, while light aligned with the direction goes through without any being blocked. Light that is in-between only has part of it blocked, with the rest getting through. But all the light that comes out is polarized.
So polarizers don't simply block part of the light, they block light that isn't aligned with them. If you have two polarizers aligned with each other then all the light that gets through the first will get through the second. If they are perpendicular to each other no light will get through.
The interesting part happens at in-between angles. Because not all of the light gets through the second polarizer, but some does. And it comes out aligned with the second polarizer.
So in the case with three, the first and third may block all light just with the two of them because they are perpendicular, but the second at an in-between angle only blocks some light from the first, and then the third only blocks some light from the second. Which still leaves some light left over getting through.
1:22 I made an electromagnet this way. just uninsulated copper wire and a screw (the screw was not pre-magnetic, I tried that)
Same. I did that when I was a kid.
That should work as long as the screw is coated[*] and the different strands are kept apart. We don't know if the bolt in the video was insulated, but the coils were all pushed together, so it couldn't have worked.
[*] I'm not even sure if this is necessary since copper is a much better conductor than steel.
The steal will still short out the circuit because it is a better route back to ground then the copper wire. Generating a magnetic field still takes energy, with can be mostly avoided if the eltrisity goes through the steal.
Are you sure the copper wire was uninsulated? Some copper wire is enameled, so it's still insulated, even if it doesn't have a rubber jacket. Enameled wire is actually the most commonly used type for this sort of electromagnetic coil!
@DqwertyC watch the video again and LISTEN CLOSELY this time.
THIS IS CRAZY, I WAS LITERALLY WATCHING THE ROCK CANDY VIDEO BEFORE THIS
Recommendation algorithm is just working as intended
NOT GONNA EXPLAIN THE LIGHTNING THING??? TF BRO??
Watch slow-mo videos of lightning. When lightning approaches the ground, objects from below send lightning "feelers" toward the lightning until they meet in mid-air. Sometimes these reach the clouds and form upside-down lightning near the main lightning.
I'm not going to say I was fooled by the first round but I will say that I am fairly certain that you can buy wire with a thin invisible enamel on it. so I am sad. ):
Please keep doing this series, it is the best!
I'm second.... Oh no, i have become what i hate the most
the first one confused me, most electromagnets use anneamel copper wire (not sure about the spelling on anneamel) which has a thin copper-couloured insulation
You mean enamel?
Lightning meets in the middle, first one is wrong
Prefect score, though I was pretty torn on Round 3 between all wrong and bubble wrong, but I ultimately went with bubble wrong as a 50/50 guess; either way, I was certain that the bubble thing was false, so I'm taking that as a W.
2:32
This is NOT true
If the polarizers (not polarized lenses, idfk what you mean by that anyway) are linear polarizers, like you suggested by the initial statement (that they would block all light when placed perpendicular) a third linear polarizer at an angle would NOT change the circularity of the polarization, and ALL LIGHT WILL STILL BE BLOCKED.
What you put inbetween was either a circular polarizer (which is a quarter wave retarder after a polarizer), OR just a retarder. This means that the light gets circularly polarized and light will pass through the third polarizer at a quarter of its intensity.
I definitely knew the popcorn kernel one from that NPC streamer fad from a few months back. Pop! Amazing!
Probably c
My guessed before hearing the answers
Round 1: The copper wire would need to have been enameled to prevent shorting. You specified it was bare. A clever trick question but can’t fool everyone.
Round 2: The polarizer one is fake. The middle filter is one that rotates the polarization; like a sugar solution or liquid crystals. It’s not a polarizer as you said it is. I was wrong. Well, we come here to learn, don’t we?
Round 3: A is fake. The straw will roll in the direction of the greater surface tension, where the bubble is intact. The stated prediction is opposite to what will really happen.
Absolutely not needed to have an insulated wire. I have done many times and it does get hot fast. 😂 Jaw Dropping dude is slipping. Lightning will only go up when ⚡ is going down first. Coming down first is absolutely needed.
0:58 That's kinda lame. Usually wires looking like that are insulated and it would work. They have some kind of thin wax/plastic layer on them.
There is copper wire that is varnished and looks exactly as the one shown here and it is posible to make an electromagnet with it, being fair he did said "bare copper" but sincerely I've never seen bare copper being used for something, there must be bare copper wire, but most you'll see will be varnished.
If you have seen an electric transformer or a coil they use the same kind of wire and work on a similar basis to the electromagnet (at least the transformer).
I failed the 1st round I can't fail the 2nd I think it is QA: the other side and C is fake. QB: B is fake. Qu-C: same as last Round 2:31
I didn't know that about Coke and Diet Coke but I knew the straw would move to the left, so I got it right. Still, that's interesting.
Talking about the direction of lightning can get very pedantic very fast
Ur my favourite UA-camr and the 3rd person I’ve ever subscribed to (I have used UA-cam for 5 years)
I wasn't watching, just listening. This isn't fair.
You tricked me on the first one T.T
You should make a round where all experiments are true, but the reasonings may be trash, or vice versa: all experiments are trash, but the explanations for the results are possible to be true
When you've got no fucking clue, always choose A.
This is how I aced this.
Round 1, 3 is wrong but only because it doesnt mention that ⚡ only goes up from ground when it also comes down.
doesnt lightning technically always meet in the middle, coming from the ground and the sky at the same time????
Lightning actually only strikes 2 ways from the ground to a cloud or from a cloud to a cloud
VICTORY!!! Got all 3 right 👍
Round 1. I chose C (loss)
Round 2. I chose A (win)
Round 3. I chose A (win)
Overall, a 2/3 (win)
These videos teach me stuff and I really enjoy them! Good job! Keep up the great work!
Round 1 doesn't count. He cheated as most wire is insulated, and he didn't disclose that he was using uninsolated wire.
@@TomsBackyardWorkshop He sad "bare copper wire" at 0:10. Doesn't it mean the same?
Picked B all three times... And now I feel stupid.
Excuuuuse me for assuming the copper wire has insulation
But how does lightning strike from the ground?
Dude You Should be a Science teacher. What the hell you are a Science Teacher
NO WHY DIDNT YOU EXPLAIN ME THE POLARIZED THINGY
Is there an in depth video for 2:34? I don’t understand how lol
part 3 is cheating actually
Can you explain how lightning shoots up?
Guess:They are all correct, except that lightning always strikes from the ground if concerned with the path of electrons.
Damn it! The isolation!
The jump cuts in every video on the last one messed me up man.
i just guess the answer by guessing which is easiest to fake bruh
Were did you get the GUINNESS
I only got the last one right through context clues
Homie didn't even try to fake the videos in round 3
The "bare" part was a trick because that could mean a few things and if you wrapped the screw in something, then space the wire properly, or if it were enameled (still no insulating rubber), or had paper spacers it would work. Also, the rock candy is not easy to grow. I've done it before as a kid, it didn't turn out like store bought at all. I'm curious if lightning strikes from the sky down more or from the ground up to the sky more often or if it is about equally likely.
Bare wire means bare wire, not enamel. Plus, it was obviously not spaced properly and if he had used paper spacers, he would have said it. What's your problem? 💁♂️
Caught cheating again!!! I've called you out on this before. The balloon debacle should have taught you a lesson. Come on man, you're throwing off my 'kill ratio'. 😂
Hi love ur vids
Lighting only goes down he’s wrong
This was a good one!
I cant tell whats real anymore anyways
bruh i thought he was using magnet wire
I’m so going to try that rock candy
Well I failed, 0 out of 3
Yay I actually got the last round perfect even with explanation! Very cool video as always :)
C - he was a bit wrong.
A
A - easiest one here
number 1 is fucked up lol, having only seen textbook examples i wouldn't knew if it behaves differently
Do a face reveal on 20000 likes
I only really got Round 2 correct because I knew that A was WAAAY easier to fake than C.
This is the first time I've gotten two wrong, but I'm pleased that I've learned something. Though failing to spot that the copper wire wasn't insulated is definitely on me
the copper one was hard
Final score: 2/3
1.A is definitely fake at least as described. Iʼd think it was possible you misspoke but Iʼm pretty sure both the others ares true.
2.C is my guess but I wouldnʼt be surprised by A
3. Neither A nor C seem real. Iʼll go with A.
So obvious it’s c
First round is wrong
Yes I got all correct
The first round, the electro magnet. That could have been enamelled wire, which can be used to make an electromagnet.
Lightning is striking down and up everytime at the same time. It can't come from one direction.
Cheater you didnt say the wire wasnt insulated. I have made electromagnets using this method.
he did, he said _bare_ copper wire
@@LineOfThy after
@@TomsBackyardWorkshop no, he said it before
0:20 0:43
you got me >:P
2/3
b on 3
Bare copper wire . YOU GOT ME 😂GG
I'm here to get a dose of science trash immunity
The trick with three polarized filters works because a polarized filter will block all light perpendicular to it and allow light parallel to it to pass, meaning if two filters are perpendicular to each ither, they together block all light. However, if you add a third filter at 45 degrees in-between them, then the middle filter will rotate incoming light into its plane, and the third will do the same.
It's literally how LCDisplays work XD
these are all so cool! i love it!
3 for 3
Too easy. 😅
Love your videos
For the first one. I come here for science challenges. The "bare" part being the trick made it feel like an English challenge.
1:14 bad example, many of these copper wires have layer of isolation allthough its clear to see through, it still is an isolation
first
