HOW DOES IT WORK?

Left to itself, hydrogen peroxide slowly breaks down, releasing oxygen. The yeast produces an enzyme that turbo-charges the process, causing it to break down extremely rapidly, releasing mobs of oxygen all at once, as well as a bit of heat. The dishwashing liquid captures most of the released oxygen, trapping it in millions of tiny bubbles – far more than can fit in the bottle so most of them are forced out – and up!
