What about a water bottle rocket ?:-

"" ROKIT is a precision water rocket used by schools and colleges throughout the world to demonstrate Laws of Motion.

Attach the Rokit to a standard plastic fizzy pop bottle, part fill with water and use a cycle pump to power it for automatic launch!

This exciting kit has the capability of providing repeatable experiments. Rokit flies to around 30 metres (100ft) which creates great fun in learning science its a valuable and visual tool for all levels of science education.""

liquid nitrogen, that will make a lemonade bottle go off with a bang! they will fail at about 10atm, so you get 2l of gas becoming 20l very rapidly!

I know of one pretty cool one.
Sulfur (available in hardware stores)
KMnO4 (Pottasium Permanganate:Available at any chemists or pharmacies)


This is the standard ratio of mass. I have played around with different amounts and have given different results. It acts like flash powder too, Soemtimes it is very bright and slow (usually with more sulfur....sometimes it is quick, sometimes it goes of witha flame like a rocket engine and it hisses. Soemtimes it is like a firecracker throwing sparks around. All the detonations i have conducted have been with strong plastic bottles at small scale and at a distance. Next weeek i am doing a 250 ml hard plastic bottle. I will reply with the results. Ussualy it makes a flash and a loud thump with a 50ml bottle. I wonder what will happen....[}:)]
