Nuts

Not quite a jetpack but very close
fantastic
Stuart Ross (a Brit) has "flown" the first European Rocketbelt recently!
Bottle rockets were the subject of my Physics A-Level coursework.
0-200MPH is 1/4 second
So what do you think he said at the end???
he was probably a-wash with emotions
One to remember for when you have to organise a last minuit activety for a bunch of rowdy cub scouts.
I've run some summer schools where we built and flew water bottle rockets. We joined 6 x 2 litre coke bottles end to end. Very tall rocket. 120
psi gave about a 6 second blast. Very high altitude and covered the length of a rugby pitch.
they are very easy to make, they are based on Hoselock garden hose fittings. Bloody good summer activity !
The Clark cable tie launcher is far superior to hose fittings.
Google Search: Clark
cable tie
And this place:
http://polyplex.org/cjh/rockets/
which I believe is the source for the Word Doc above has all sorts of instructions for building and shaping the rockets.
