put some strips of aluminum foil in the bottle and add a little HCL ("The
Works" toilet bowl cleaner works real well) tighten the cap, give a shake,
and toss out back. In a few minuites there will be a real big "BANG" when
the bottle explodes from the reaction. be sure to stay clear! --dave


You'll want to review your inorganic chemistry. It's hydroxides you're
after if you want to generate hydrogen. Lye is the preferred for its punch
by weight. Drano and some other drain cleaners even include some aluminum
chips for the foaming and the mechanical action it generates.
