can you guys give me a list of some chemicals that expand when mixed? the reaction's can't be combustion reactions though. that's the only limiting factor.

Have a look for the "elephant toothpaste" trick. There are loads of videos out there.
Dried beans expand when mixed with water. Stop me if you've already seen this one:

Add vinegar and sodium bicarbonate(baking soda) and you get the classic erupting volcano. It that what you mean by expanding or stuff that foams up like polyisocyanurate spray on foam insulation. There are also polyurethane foam insulations too. They really are reactions that produce gases to make it foam.
even normal Gorrilla Glue does the expanding trick :-)
Potassium Iodide and Hydrogen Peroxide. You cant use just 3% Peroxide from Publix, you need 8-30% from suppliers. Try United Nuclear.com
