Foam Recipes

Vinegar + Baking Soda is one of the staple science tricks of Kitchen Chemistry books.  Here are some fun variations.

1. Water + Baking Powder.  Not as foamy, but a little safer for small kids (no eye-stinging vinegar).

2. Vinegar + Baking Soda + Dish Soap.  The soap traps all the CO2 gas, and you get much more foam.
