  • Amazon.com: Potassium Iodide, High Purity USP

    This would be 33grams per 100ml which is an amount that is easy to measure. You will likely need much less than 100ml of solution to get an impressive amount of foam. Probably 10ml of solution will do the trick with around 50ml of 35% H2O2. Much more than that amount of H2O2 and you will have a large mess to clean up.
