Background Elephant's Toothpaste. 30% hydrogen peroxide is added to a glass cylinder containing a concentrated aqueous mixture of potassium iodide and dishwashing soap. The iodide ion catalyzes the decomposition of hydrogen peroxide, generating oxygen gas which causes the soap to foam up and shoot up out of the cylinder. If you want to give your foam stripes like some toothpastes, put the drops along the inside rim of the bottles mouth.
