Anyone remember zinc dust and sulphur?  Reading this thread, it's a wonder any of us survived childhood!  ;)

Zinc dust and suphur would get you into orbit - used as oxygen free rocket fuel IIRC
Burning zinc metal produced floating white tufts of zinc oxide called Philospher's Wool.  Who says chemists have no soul?

Picric acid was another of our chemistry teacher's favourite bangs, a tiny bit in an aluminium foil wrap over a Bunsen burner if I recall.

We also used to have fun filling balloons with hydrogen by reacting sodium hydroxide with milk bottle tops.
