Don't forget to strap different things to the rockets, and put some down some drains, and detonate one of the massive ones (the 'mine' as we had) in a pumpkin if you've got one hanging about from halloween.

What you shouldn't do is aim them at trees, try to do things too quickly and knock one over smashing a distant conservatory, or have one hit off your roof and then slide down and land on your head (yes, I'm an idiot).
