If you want a bulk DIY foam thing, I recall a plastics vendor I used to
deal with carried something called a "froth pak" that was basically two
small tanks (like freon or consumer helium comes in) and a hose and
mixer gun assembly. The folks on Mythbusters seems to use the same
product from time to time. Presumably some net searching should find
better references to the stuff.
