- Chief Scientist Carl Nelson shows us an extreme science project using hydrogen peroxide to make foam.
It turns out that the bottle of hydrogen peroxide you have in the bathroom really does nothing for small cuts and scrapes. Check out this article from the New York Times that talks about how peroxide use for cuts is really not all that effective.
Of course don’t miss our video below that shows what you can do with concentrated hydrogen peroxide.
We’ve received a few questions about hydrogen peroxide and it’s effectiveness on small cuts and scrapes. Head over to: imaginationstationtoledo.org/c... to find references on the topic.

The answer for those in chemistry.
Initial Appearance: 35% hydrogen peroxide along with dish soap in a tube with hydrogen peroxide.
Observation: There is a tube with 35% hydrogen peroxide and dish soap gets pour and mixed with the 35% hydrogen then a catalytic get poured into the tube making a foam like substance come out of the tube.
Type of change: chemical change.
evidence: The 35% hydrogen and the dish soap along with the catalytic make a foam substance come out of the tube.
You dont know how much u helped cuz i frfr qint wanna do this bro 😭😭🙏🏾🙏🏾✨💀

This is EXACTLY what I have to answer LMAO
everyone is here for chemistry
ong
Yup

Pretty much
send the answers
Pov: no one will shut up about being here for chemistry
Yo guess what
I'm here for Chemistry
YOOO me too
Mohona Alam ooh ooh I know ummmm MICHAEL!
@@qwerty555_ !!
Initial Appearance- red liquid and a black liquid
Observation- they poured dish soap in both, then added peroxide and it released a bunch of oxygen gas
Type of Change- chemical change
Clue- its irreversible
ly
thank you so much
Omg tyyyyy
tysm ur a god
i’m doing this same paper rn 😂
initial apperance: large foamy mess that looks like toothpaste.
observations: when the hydrogen peroxide comes into contact with the yeast it starts breaking down into water and oxygen.
type of change: chemical
clue: color change, gas formation
Thank you so much
thanks
thank youuu
thank you so muchhh
I wonder what the Janitor's reaction was when he saw the reaction going down!

don't diss school people if you can't spell here
we must thank emani williams for dedicating their time to actually watch the video instead of going thru the comments like we all did, thank you emani
thanks for this video it's the one who make my team win in the science fair
it looks like how titans might be made
HEY MATPAT
That's really cool and I really like the blue one

2:23 is WOOOO timing
Can you say how you did it? What did you use an happened please tell me!!
Chemical Change because a new substance is added which reacts by forming bubbles/gas.
thank you
Hydrogen peroxide is a cytotoxic agent (meant to destroy cells completely, compared to acid it may cause an effect of 'oxidative stress').
"H2O2, a highly reactive agent, can react under certain conditions with a variety of cellular components. These reactions include the lipid peroxidation of membrane and hydroxylation of proteins and DNA. The reactions can take place in the presence of oxygen and are fairly rapid, the H2O2 being converted to water and oxygen. Experiments were carried out in vitro to assess the ability of this agent to destroy cancer cells without generating dangerous by-products. The direct administration of aqueous H2O2 into solid tumors has the potential to cause tumor cell death."
+Sedokun I was very irritated by his comments on h2o2. had to read the comments I knew someone would point out the health benefits
+Magnum Opus Productions H2O2 naturally produced in human's body. Here's a great article about it: www.febsletters.org/article/S0014-5793(00)02197-9/abstract
Finally someone who understand it! And also H.P can kill any type of organic matter when it react with iron which produce Hydroxyl radical which is highly reactive and then at time of this thing produce any organic matter to come in contact with it will eventually be dead and assured. That's why bacteria which use a lot of iron can't make it in the people's body where H.P is abundant (I think)
What are all the materials necessary?
I wanna make that for mt homework but what do i do to clean it up? Since it includes chemicals
What were the quantities used of Hydrogen Peroxide and Potassium Iodide?
SHE NEEDS TO PULL UP HER HAIR. SHE IS BREAKING CHEMISTRY RULES
Does the amount of detergent affect the amount of foam formed?
Does anybody else want to eat it? O_o
It certainly does look delicious, judging by the bright colors and texture. If I didn't know better, I'd say it was a huge glob of Icee...
Omg I did
eating a 3 hundred degree paste that looks like BLOB is not the best thing to do
@@CatMaster90001 very true sir
How does the soap capture it?
My school's chemistry club is planning on doing this lab as a demo! :) How do you properly clean this up?
Hi maliktuber, we usually put down a layer of garbage bags or plastic sheeting to capture the bubbles and then throw that in the trash. The end products are water, soap, food coloring and the potassium iodide. We wash the glassware with an excess of water.
--Carl Nelson, Chief Scientist, Imagination Station
Where can I buy all this chemicals?
missed the money shot.
Did you have idodide or yeast in the bottle already?
Hello, we're trying to do this in our demo, can I ask what liquid is inside in the beaker and flask before you put the soap and the hydrogen peroxide?
Jonathan Vasquez Potassium Iodide I think
It's just coloured water (food colouring)
What can we use to disinfect then?
am i the only one who slammed the breaks when she said "imagination station?"
excellent scientist!
What molarity is the potassium iodide solution?
Which salts did they use (Red and Blue)?
Love the thumbnail
How do u clean it up if it’s hot?
Can this be used to make Aircrete by mixing into Portland cement slurry? Where can you buy 35% Hydrogen Peroxide?
I like this stuff! cool video!
Maybe it doesnt clean wounds, but it's definitely a biocide and can be used to sanitize surfaces. You still shouldnt use it to disinfect your wounds though, because it doesnt just kill bacteria, it also kills the human cells, which slows down healing (which means a higher risk of infection and more scarring).
Nahhhh I use 3% all the time, and it works very well. Reduces the war for your body to fight. Especially because you can't actually see what viral loads, or bacteria strains got in. Plus I nearly cut my finger off so the doc submerged my hand in H2O2, and it stopped the bleeding completely. Finger healed up with no mark. Was astonished.
How dense was paste?
Wait a school video where the comments are open. How strange
Anybody know what's in the beakers other than soap and food colouring?
The laundry at my workplace uses hydrogen peroxide (50% H2O2 in the 10 litre drum) as a bleaching agent.
Yeah we also use hella concentrated h2o2 for rockets
What is the catalyst?
Where does one find the catalyst? This can be great to mix with concrete to make aircrete.
What is the catalyst..?!
What was the catalyst?
Hi! Where can I buy the potassium iodide?
abneyk1 we purchase our potassium iodide from Flinn Scientific. I don't think they sell to the general public, however, a google search will return some vendors that sell it.
-Carl Nelson, Chief Scientist, Imagination Station
What change is this?
which chemical gas law is used here?
Hi could l know what react with hydrogen peroxide soap and ??? Ian ask about the substance in the conical flask
Potassium iodide
Thank you
Can anyone tell me how much catalyst is needed for this ? Tryjng to get big eruption
amazing
so cool!
That's pretty cool
Will be the same effect in case of only 3%? Could some one claim that 3% is not going to be deomposed even if heated up to 100+C?
60fps on a video from 2012? Nice
awsome
STATION #:3
INITIAL APPEARANCE: Blue liquid, and red liquid, there both in tubs, and there is a liquid that is hydrogen peroxide.
OBSERVATIONS: At the end the liquid’s is gone and there is a thick kind of paste that is red and blue from each liquid. At first it rises and then it goes down.
TYPE OF CHANGE: Chemical change
Good lad
thanks daddy
Thank you!!!!!!!!!
Can we touch foam so formed with bare hand plz anyone reply
Hidrogen Peroxide doesn't directly kill all bacterias but it does kill anaerobic bacteria because of the oxigen.
Hello, everyone! Im asking for your help; i am having hard time with my assignment.
Question: some chemicals, like hydrogenperoxide, are prone to decomposition by photocatalysis. How can you prevent photocatalysis?
Erm.... reducing UV exposure I'd assume.
Put it in a dark coloured container
Maybe rry 35% Food grade peroxide doc?
Lmao i kept hearing catalyst and when he kept saying it the whole time i was thinking so what catalyst was used?
+++++
a little confused on what role the soap plays. I thought the oxygen was stored in the peroxide itself and that a O2 was released as the peroxide converts to water.
I think i get it. the soap traps the bubbles from bursting and releasing the O2 into the surrounding air.
soap makes the foam i think
Incredients?
its a chemical change btw
Thanks

So that's how you make slushies................
is this physical change or chemical change ?? I'm bad at chem
chemical
Should I use liquid or powder?
abneyk1 Either would work, however, I'd suggest buying the powder and making a concentrated solution. We typically use a 2 molar solution.
-Carl Nelson, Chief Scientist, Imagination Station
+ImaginationStationOH in layman's terms... What is a 2 molar? What do I mix the iodide powder in? Water?
I can see steam on top the red one
What is the Catalyst he is using?
Hi ThomasMattOnline, I used potassium iodide as the catalyst. - Carl

Trapped in a car? Use this method to generate Oxygen.
i think its funny i can here some guys like it to in the backround LOL
That is neat,but are you able to touch it?😮
Gabbriel Simmons you can touch the foam after it cools down. It's pretty hot initially. Of course there is a lot of food coloring in there and some iodine, both of which will stain your hands. -Carl Nelson, Chief Scientist
What was in those Test tubes, *BEFORE* he put the H2O2 in it?
Oops, i Meant what was the *Catalyst* that he?
duke john Potassium Iodide.
It's so fluffy *_*
They should mix it together
throw a match on it
+suncu91 Well, unfortunately that would be a little underwhelming here since while the foam is filled with oxygen, there is no Fuel to actually combust. You need Fuel, Ignition source and oxygen for something to burn. Here at match tossed into the foam (soapy water) would burn a little brighter for a second or so and then be extinguished.
Carl Nelson, Chief Scientist, Imagination Station
+ImaginationStationOH it also generates hydrogen
+Leo Madero I don't think so . The decomposition of H2O2 produces O2 and H2O.
canoenew probably i dont remember what made me think that it did
Physical or chemical change?
@Cynara Clay thank you
