Sounds fun...
but I'd rather blow up the Lib Dems. This year am planning a 4x rocket 2x can extravaganza. Need a staging / testing ground this time - any ideas as to a remote, safe place with plenty of natural hidey-holes?

Somerset - plenty of left over WWII pill boxes.

Add fins
You need the fins to be well behind the centre of mass - which shouldn't be a problem with a fuck-off can at the front! Maybe remove the stick and attach 3 light but rigid wires with tincan fins at the end. The rocket will then fly much more stably (and will steer *into* any wind, by the way).

You'll also need to keep the centre of mass on the same line as the thrust. May I suggest two or more smaller containers, strapped symmetrically around the top of the rocket?

This all sounds fantastic..
but I'm worried that if I do actually acheive a decent amount of height and speed, the device could explode nowhere near the launch pad. I have horrible visions of dousing some poor OAP's thatched roof in liquid fire, and the subsequent local news stories that would follow.

I guess we could blame terrorists.

I like this a lot, but there is one thing to learn
The thrust from your single rocket is tiny, hence the thing falling out of the sky. You need to double or treble the first stage. Otherwise you will have it hovering about at ground level until the final explosion. Good luck, wear goggles and post the video here.

If I were doing it
I would fiddle the fuses so that the rockets went off in two stages, sending the whole assembly higher and removing the "holy shit it's coming back" problem.
