In a new video you can see how Netflix presenter Nick Uhas makes 200 cubic meters of elephant toothpaste. A world record!
Elephant toothpaste is one of the best known chemical experiments and can also be created at home. Put hydrogen peroxide in a conical flask and add a small amount of detergent. You then add a catalyst such as potassium iodide or yeast. A series of reactions take place between the hydrogen dioxide and the catalyst. The catalyst, for example, breaks down hydrogen peroxide into oxygen and water. The soap mixes with the oxygen and the water, thus creating a giant mousse.
Of course a nice video was made of this experiment. Skip to 9 minutes to see the actual experiment. In a short time the entire environment is covered under a thick layer of foam.
The question is how long this world record will remain in the hands of Nick Uhas. Science Bob will no doubt make a new attempt in 2020.
