See the full instructions from ScienceBob here , Nick Uhas and David Dobrik stunned the internet with, Before their attempt, science YouTubers Mark Rober and ScienceBob did their own, If you want to replicate their attempt on a smaller scale at home, ScienceBob, A 16-ounce plastic soda or water bottle OR a bucket that size, A small cup to hold your yeast and at least 3 tablespoons of warm water. But Home Science Tools' products and service can handle it. Swish the bottle around to mix the ingredients. Hydrogen peroxide breaks down into oxygen and water. 5 years ago. Want a real chemistry set for your kids? 1. Then, a catalyst, often around 10 ml potassium iodide solution or catalase from baker's yeast, is added to make the hydrogen peroxide decompose very quickly. Give students a solid chemistry foundation with the hands-on experiments in this complete lab kit! Pour 40 ml of dish soap into a large graduated cylinder or large beaker. Science can be messy. Mix 10 g of potassium iodide and 5 ml of water together in a small beaker. 30% hydrogen peroxide elephant toothpasteAppearance > Menus. Although potassium iodide is used for a big WOW factor, using yeast is more kid friendly! The soapy water traps the oxygen, creating bubbles, and turns into foam. The reaction is catalysed by Potassium Iodide. Add the 30 % hydrogen peroxide into the jar. Mix 10 g of potassium iodide and 5 ml of water together in a. Another important thing to note is that the reaction is exothermic, meaning that the foam will be hot. As both videos exhibited, all you need to do to jump-start the chemical reaction is combine the catalyst with the peroxide mixture. Also be aware that peroxide is acid stabilized (a small amount of acid is added to prevent decomposition) and at pH of about 10 it will decompose on it's own in a matter of days. WOAH! About 50 ml of concentrated (>12%)[5] hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide.[2][3][4]. How to make elephant toothpaste: (click supplies for ordering information), 50 ml 30% hydrogen peroxide (I use FLINN Scientific for school), (If 30% is not available, use 150 ml of 12% Hydrogen Peroxide), (If potassium iodide is not available, use 1 Tablespoon of dry yeast mixed with 3 tablespoons [15 ml] of water), 2000 ml Graduated cylinder (or large beaker).
