This is another alternative to Glycerin/Potassium Permanganate reaction. :)

@dragonridley indeed. Anything lower in the reactivity series than iron would produce a more violent reaction. It still wouldn't be the thermite reaction.

Other demonstrations show that other reactions between aluminum and a metal oxide can be just as effective, if not more so.

@dragonridley Then it wouldn't be thermite. Thermite is specifically Iron Oxide and aluminium.

How do you make Chromium(IV) Oxide ??? I can make Chromium(II) Oxide by decomposing ammonium dichromate...

any reaction that gives of heat to the surroundings is exothermic

This reaction is exothermic right?
