Wait... my entire life, I've not known "Adsorb" was a thing, I'm deeper for having watched this just 40 seconds in! Awesome! Thank you!
Great job freaking me out. I thought something was wrong with my computer when it started to fade out haha
freak out on my phone too
Adsorbing....huh. Learn something new every day!
Thanks Lauren!
That was my favorite takeaway from this episode's research! /Lauren
BrainStuff i was totes about to be like SHE SAID ADSORB LOLOLOLOL but then i was schooled. and for that, thank you. also.... youre hot. you can adsorb me any day.
@@readyrepairs wtf
I thought this was good as well. I enjoyed learning this. (:
@@WarriorsPhoto you YOU reminded me on that man how could you?
I use to dry my shoes after a good workout. Works, gets rid of odors and sweat inside the shoe.
I seriously wouldn't have mind it if she had gone on about all the other uses for silica packs for about another 2 or 3 minutes. That would be so helpful
Exactly.
Ah. A five minute man
Azrael That’s better than a minute man. 😉
if your phone has moisture inside it you can put it in bag with silica gel
😢
When I worked at Circuit City (to date this story) one of our employees wanted to play a prank on the Manager of Televisions. She slipped silica packets into his coffee. He saw her do it and walked over and picked it up, slowly bringing it towards his mouth.
He looked at her and said "Man I was just unpacking stuff and found some of those silica packets." She smiled and nodded. He continued. "Crazy how they are extremely toxic."
She panicked and immediately tells him that there are some in his coffee and that she thought they were harmless. He then takes a swig and all the color from her face runs out.
For the rest of the day he would feign gagging anytime he walked by her and she was in a packet the entire time. It wasn't until close that he finally told her "Silica is sand. Sand is harmless."
Good times. I miss that group of weirdos sometimes.
boomers joking around at work by poisoning and borderline killing each other
gigakek
5 years passed since then, fun is now illegal in 2020
preventing camara lens fogging while they fade out? well though of editor, well thought of.
You've used them for that? (:
Good bit of info and I am glad I watched this video. Thank you for the information.
I found packets of silica gel in the hunger games game
It said do not eat
I was like "WTF"
Thank for the video always wondered how exactly it worked lol
Your explaining is so easy to understand. Its makes is Interesting to listen sometimes boring subjects.
Nicely presented!
Great explanation!
Well done. Thank you.
Thanks for the help. Adsorption thing was really cool.
The end was terrific 👍🏾
Lol that was pretty funny the list of things that were useful for reusing silica gel
Awesome video
That was super helpful thanks!!!
+Cyrielle H ^____^ Thank YOU for watching! /Lauren
Thank you. This is more informative. Could you also explain how silicone is produced and different types of silicones. Why it is largely used as sealants.
really good
very interesting
there should be a video on the difference between absorb/adsorb. common misconception that i was unaware of
Thank you for being concise and to the point without yada yada yada.
Someone copied this video lol.
The similarities between the start part of this video above and this one (watch?v=2OsLyBXH3rA) made over 2 years after this one are shocking, especially the "adsorbs vs absorbs" point. I don't understand why people would do this shit.
Guess it means you're doing something right :p
oh hi GradeA lol
WHAT ARE YOU DOIN ERE
DAMNN
_"this video above and this one (watch?v=2OsLyBXH3rA)"_
Thanks for posting a link to _this_ video, I would never have found it.
Grade!!!
what is the title? im on mobile
Good Video, One Question. Some desiccant packs can keep the RH levels to 70% and another may keep it at 55% RH. What is the difference between the two? The material used? Thanks
They are fun to use for Macro Photography too Lauren.
When I put one of the silica gel packs on the side of my lower throat causing issues like sneezes, gagging, can't breathe, all from a shift of the hip by an Osteopath years back, which caused major breathing issues and due to a bad massage it can also shift this energy back complicating the breathing, but for me one little silica gel pack on the skin calms things down.....but please know your severity, for me it's only one side.
Great Video, hey whats the name of the music in background?
cool video
Lauren ❤
love the Rust Cohle reference. ha ha ha!
that's helpful. well I'd like to know if it helps to dry your hair.. like it's you place 2-3 packets in your hair for a few minutes would it adsorb all of the water and make hair dry ?
I'm going to try to work in the word adsorb sometime, and watch people's confusion as they try to figure out why I'm saying absorb funny.
im just curious but thanks for this vid
Awesome nod to True Detective's Rust there. :)
SG is packed into edges double glazed window panes and causes streaking when saturated, is it corrosive
to glass or only abrasive so easier to clean off?
do you have to heat it inorder to be reused. or can you just leave it and wait for the room to be hot (like during summer)?
has it been used in textile and fibers?
I imagine it can be a game changer for humid places!
2 smart for me lol.. thnx for the nice lecture.
Fantastic presentation! Cute presenter also!
So do you open them or leave in their bags for use?
Hola tengo de conocimiento que la SILICA también puede usarse como clarificante en aceite/mantecas es cierto?
Tienen algún material bibliográfico o estudio que pueda revisar respecto a esto?
Hello, I am aware that SILICA can also be used as a clarifying agent in oil/butter, is that true?
Do you have any bibliographical material or study that I can review regarding this?
Is there difference in adsorbing efficiency between the clear plastic, paper and cloth bags they come with? Like how can the moisture pass thru the clear plastic bags that some silica gels are packed in?
If I'm being honest this video only made me want to eat it and see what happens
I use it to get the moisture out of my hearing aids :P
this seems to be good for use with items that are packaged or sealed off from the atmosphere. But I have seen people dry out wet cell phones with desiccant. How is that better than putting it in front of a fan? A fan will whisk off any water molecules that evaporate from the surface. Desiccant does not "extract" moisture, just absorbs it after it's come out of the item. A fan will move are into nooks and crannies the desiccant can't get to, moving the molecules out into open air.
I want to make water glass with silica jel and lye. How would one determine the quantity needed to make some fireplace bricks out of silica gel, lye and Vermiculite or Perlite?
I get a little pouch of the stuff every time I open a new hard drive at work. I've been throwing it out, but maybe I should be saving it and learn how to reuse it properly
you should eat it every time and see if you die. do it for science.
readyrepairs You still life or did you try it ?
Is this the same as hydrated silica? Would u add these to water or? How much per gallon? would i use a food grade?
the background music! haha
How can we tell if it is saturated?
I was wondering if salt shakers could have things like vitamin C caps inside.
(I'm concerned about using the little bags and them opening and salt mixing with the silica).
Btw, if I load my biceps with silica gel, will they adsorb enough moisture to appear as full and amazing as Lauren’s thingies?
How often would you put the silica gel in the oven for?
Adsorption and absorption i know little surface chemistry
Can we keep in grains to control moisture?
will it kill little bugs if you open it up and sprinkle it?
how to know that I should heat silica gel now for reuse?
Can it absorb through plastic? Like if you put it in a mini ziplock bag and then put that ziplock bag into whatever that you wanted to be dry. The ziplock bag is sealed
Does silica gel can prevent bad odor?
Does it lose the humidity ?
Venice should probably invest in silica gel
I have a question, which I've always wondered about. How is silica gel useful, when its moisture adsorption properties get maxed out. I'm thinking, I have a keyboard at home in a flight case, I never use. So I stuffed some bags of silica gel in it. But how long are those (same) bags going to keep the electronics viably dry?
I used some rather big ones in a convertible sports car that I had cause the soft top leaked... never once had mold
The fact that silica gel can hold 40% of it's weight in water does not equate to 40% relative humidity. So my question is then where do you get this 40% relative humidity figure?
that is a good question.
Just coincidental numbers, based on it's ability to grab the molecules.
They just sounded odd.
Well the numbers have to be based on each other in some way and she even said thus when transitioning from the amount of water it can hold to the relative humidity it can achieve. Regardless, I don't see how you can conclude this 40% RH statement. RH changes with temperature, pressure etc.
because they put enough of it in there to absorb enough moisture to average out to whatever relative humidity they want. even if silica gel adsorbed 5%... if you put enough in there.. it would be able to reach 40%. derp.
How long does it take to heat it at 150 celcius to reuse them?
Informative. Thank you. For senior citizens and people with English as second language, little less speed of speaking will be immensely helpful, especially because you want to spread knowledge around the world. Will it also be possible to tweak down the back ground music? Thanks for. Your effort.
Watch at 0.75 speed
Ok if i have a damp shoe and it stinks...can throwing in silica gel packets from my vitamin pills remove the smell?
yaaaaay more Lauren ^_^
My friend opened one and she died and I keep finding them in my home
Cool =- how to make silica gel interesting !
+Cameras Direct ^___^ Thank you! /Lauren
Laauuuuurrrennnn....😘
I recognize this song from somewhere.... WHERE IS THAT SONG FROM?!?!
I put them in my sealed ammo boxes to keep my .22lr ready for the zombie apocolypse lol
Preventing rust on weapons that you safely lock up and forget about moister!!!! Tip: put mimi cat litter in a stocking....or a coffee filter or tea bag and throw it on there with them. Cheap extra piece of mind
I use silica packs for my plant seeds so they don’t get moist in storage 😊
can you use it to dehydrate fruits and vegetables?
Vogelbaum is German for BirdTree! Your name is adorable Lauren! :)
+traveric3 Right?? I love it. ^__^
There was a pocket in front of my pillow I've been sleeping here for months
Nice shirt
is this Damprid?
First thing I thought of was Game Pidgeon Cup Pong
Is the s or c silent in the word scent?
Technically the c.
1:47 Do any of the other "less than awesome side effects" include hallucinations? Asking for a friend.
if your phone gets wet, instead of putting it in a bowl of rice, put it in a sandwich bag with a couple silica packets in it.
That makes sense! I hate it when my waterproof phone's at low battery and it says I can't charge it because there's still water in the charging port.
But I still wonder how it's absorbing the moisture even though it's sealed in packet????
I just wish that she actually explained: "How Does Silica Gel Work?". This video is more like how silica gel can be used.
I don't know whether this is absolutely correct, but I don't believe just SO2 itself is actually in those little packets. I can't imagine how it can create any external forces that can attract water. It can only trap water inside the pores and not cause any attractions. Since those silica gels balls are inside a packet, just SO2 itself would be very ineffective. I believe you need another group, namely, the hydroxy (OH) group for those packets to be useful. The hydroxy group, which has a dangling hydrogen bond at the end of each oxygen on the surface on the gel, can explain all the desired property much better than just SO2. It can form hydrogen bond easily with water, so it's already much more efficient. More importantly, though, is that it can create van der Waals forces and dipole-dipole attractions with help to draw water towards the gel.
Okay one question has there ever been any long-term studies of silica being in our food or is there simply no studies being done because there's too much profit to be made?
if profit motive were a barrier we would never have got studies proving tabacco is a health hazard, among a list of other things
Fitting to have a presenter with silicone
what happens if you throw them in the sink
The transparent gel on pen is also silica gel .
Why do Android Apps take longer to develop?
(I'd love to know, simply because I want the Test Tube App on my Nexus 5!)
theoretically, they don't. It has to do with variance in programming languages. The people who developed the iOS app were programming in either CS6 Flash or Cocoa, while many android apps are developed in Java. Differences in the languages can make it difficult to change a program from one system to the other.
I talked to our development team and they said the Android version is on the way! It may take a month or two. This could be a cool episode too so we'll add it to our list.
Is Silica Gel biodegradable or safe in the environment? Like kitty litter? I’ve been getting mixed answers.
m, cool
does silica gel contaminate water?,, let me clear my question..say u are going to drink a glass of water but stopped in the middle of the way when u see some silica gel balls in the water..now you tell your self?? what the heck?? silica gel does not dissolve in water..so what is wrong with drinking the water with out ingesting the silica gel..
I dound it in Anthibiotic
So how does it work?
Why do we sometimes feel like throwing up after a really hard workout?
Thanks Lax. I want to know the answer to this too! We'll look into it.
0:12 The answer to your question is because there both made out of the same thing lol
Im Dancing to the music because it’s the GamePigeon 8ball game love that
