Subject: hydrogen gas

A few weeks ago Modesto did a demo at a Saturday workshop in which he
blew up a balloon filled with hydrogen. I want to do the same
demonstration for my students, but I don't know where to get hydrogen
gas for little money. (I don't want to buy one of the cylinders of
H2.) Does anyone have any suggestions on how to cheaply acquire a
relatively large amount of hydrogen gas?
