Which school would let their pupils make an explosive device for a project? None. The survey says: XX - Bad excuse!

Generally such experiments would be done as a teacher demo these days...too much health and safety red tape to let kids make rocket motors I would have suspected.
Is this project really for school?

His site is http://www.nakka-rocketry.net/
The guy is pretty awesome at what he does...and possibly makes the most well engineered engines around.....read ALL of his site before even contemplating the production of a composition.
Richard casts his grains which make them a lot less prone to explosion, but is fairly risky in itself.
A very safe composition to produce would be the epoxy/oxidiser fuel grain which is cast at low temp, however you require a fairly high pressure within the motor to get these to burn efficiently, but it conceptually could be acheived with a good home rolled paper tube.
This is serious stuff...treat it with respect...and for god sakes start with paper tubes!!! NOT PVC!
You also need to set some objectives first. For instance is your rocket going to carry a payload, or is it purely and altitude attempt? And remember if you are not using 'chute's then the thing is going to come down.....and fast! Launch in a very very open space, as others will agree one of the most scary sounds is the noise of a large rocket hurtling towards the ground with a failed parachute when you can't see it!!!!
have fun, and let us know how you are getting on...and if you are in doubt for gods sake ask!
