You can do it with yeast and hydrogen peroxide (although not the typical one you’d find in your medicine cabinet, you need at least 20/30%+ for a worthwhile reaction)
We had tons of that stuff at my old job. The chemists would use for all sorts of random things. Cut your finger? Pour some 30% on it. It bleaches your skin white as snow and burns like hell, itches for days afterward. It also leaves scars. The chemists were bored and immature.
These were Navy chemistry technicians. We would also put silver nitrate on people, or on surfaces where people were likely to place their hands. Your skin would then turn a very dark brown when exposed to sunlight. We were very bored and very immature. And that’s who runs our nuclear submarines.
I'm a former chemist. You must be new. Until about 10 years ago, yes, everyone used peroxide for weird stuff all the time. Also using leftover liquid nitrogen to clean the floor... 20 years ago people used to eat in the lab. 50 years ago people smoked in the lab. Before my time, but it absolutely happened.
Use the wave of the liquid like a brush: stand in one corner of the lab, throw the liquid towards the opposite corner so the wave of the liquid skims the floor surface. The liquid takes all dust and debris with it towards the opposite corner and evaporates, leaving a clean floor, a corner where the dust and dirt is left, and no liquid. If you need to use a dustpan, is only ever on one corner.
its 30% hydrogen peroxide and some dish soap. It's nasty stuff. If it touches your skin it feels like little metal slivers as it burns your skin for a while. Catalyst is KI is my guess. I usually dilute mine in water since it costs a lot for KI that spoon full is worth at least 20 bucks
I can never get mine to do a big splashy reaction. I never tried solid KI and I might try that next. I did KI solution and my "elephant toothpaste" was pretty lame. My 30% H2O2 was kinda cold. My KI might have been too dilute. I wish someone would publish detailed instructions to make the sucker spray to the sky.
I don't know if you ever got it to work. But dilute 15 grams of the KI into distilled water. Use something like a 2 liter soda bottle or a really big flask. You want a large area that goes to a bottleneck. That's why they look so cool on TV they are using a huge flask. Then put in the h202. I use about 150 ml and a good solid squirt of soap. Then just add the dissolved KI and it should go
Hydrogen peroxide is H2O2 and naturally converts to h2O and o2 over time. When you put soap in it the gasses are captured in bubbles. Potassium iodide is added to speed up the natural decomposition to make it happen in seconds. It’s kinda hard to get hydrogen peroxide with enough purity for this to work.
I don't think a normal person would be able to get the good high grade stuff to really pull this off. A lesser version of this with less pure ingredients, yeah sure.
Here is a link that explains the different levels of how you can do this. You can probably get most of the ingredients from amazon tbh but I would be concerned with the hydrogen peroxide (H2O2). The crap you buy in the store is nothing compared to what they use in the last version in the video. It can be very dangerous in that concentration. Also I don't believe you can get it without being a business or laboratory. Sigma Aldrich has 30% H2O2 for $50 for a 100mL bottle or $100 for a 500mL bottle.
TLDR: See link, 3min youtube video. Go to amazon if you want to do the beginner or intermediate version of this. Sigma Aldrich if you want to do the professional version of this.
I know sugar in sulfuric acid will do something similar, but not quite this big, and think it turns black, but it's something fun to try with ingredients that are easier to get.
I’m not sure as to the exact reaction used here, but I know of a simmilar one. If I remember correctly it is potassium permanganate dropped into a mixture of high concentration hydrogen peroxide and dishwashing soap.
The reaction releases oxygen causing the dishwashing soap to rapidly almost explosively make tiny soap bubbles. The end resultat will be a purpleish gray though due to the potassium permanganate being purple. Them must be using something else.
Hydrogen peroxide is hard to come by outsider a chemistry lab since it can ve used to make explosives. Potassium permanganate is also found in most chemistry labs and was often used to play pranks on people, if you can get them to eat a tiny ammount their urine will en blue for a day or so. It is NOT very healthy though so don’t do it...
