There's some good stuff on there. I've only had a quick look, the metal that melts in hot water looks fun!
Neat stuff, but look for a book called "Vacuum Bazookas, Electric Rainbow Jelly and 27 Other Saturday Science Projects"
The vacuum bazooka will fire a water filled film cannister over 100 feet (straight up)

ah, if we're getting into the realms of projectiles, look up "kartoffelkannon" (german for spud gun)
now we're into the sort of technology that the army will be looking at!

Seems we have another activity for the next unofficial 101 northern meeting...
Ambis with compressors will be welcome.

Just ordered said book along with another on how to make potato cannons.......best warn the neighbours!. Clarkson had a handheld hairspray powered spud cannon on some programme he did, worked a treat it did.

I remember making something similar with a length of 6" drainpipe, a frozen grapefruit, a spark plug, coil, battery and a tin of Lighter Gas. Sufficent power to put said fruit through a door at 50 ft.
Tricky bit was getting the gas/air ratio correct.

Backyard Ballistics ?

This is the basic way we fire the rocket for the breeches buoy in the resce team I work with. There is, I can confirm, a loud 'bark' along with a wisp of 'smoke'
Lots of fun too
