I actually made a very crude one when I was quite young :bigsmile:
It was a metal tube which I squirted hairspray into, then rammed a tightly fitting potato into and put it on th kitchen stove.... then ran like hell :iagree:
My mum wasn't too impressed, but I thought it was cool :iagree:
(ok, you have to bear in mind that I was the type of kid who had a chemistry set and a microscope :o )
A couple of years ago I did see Clarkson (as of Top Gear) making a very similar giant turkey gun on his chat show. He did the same thing on bigger scale by stuffing a raw turkey into a big metal tube. It blew up and destroyed a bunch of the tv studio lighting.
It must be on YouTube somewhere.
Ah, good old fashioned home-made fun :bigsmile:
