Chemical reaction creates frothing fountain of foam

YouTuber Jacensson showed off a simple chemical reaction that produced a hefty front of foam in this fascinating science clip.

The clip, filmed near Czechowice-Dziedzice in south Poland on April 28, shows Jacensson mixing perhydrol with some potassium iodide in first a small then a large dose.

The result is a mass of foam that completely envelops the chemical containers and makes a terrible mess of things.
