Bottle rocket launch

Home made bottle rocket launch.
Total range: ~70 meters
Launch speed: ~75Km/h

A 'U' shaped pin is used to hold the bottle in place so that a higher pressure can be obtained, without it the bottle would go 10m max. The pin is a bit dangerous as the string needs a hard tug to release it due to the pressure, hence I am pulling the pin and my youngest brother is doing the pumping.

Sorry for the poor quality, we filmed this with a webcam and laptop, access to a proper video camera was not available.

I'll put together a small site with the details of my launcher, it is not brilliant, but it works and could be made better is we had put a little more thought in to it before we started construction.

I'll PM you the link when it's done.

Yeah, they're pretty cool when you have them working well.

You should see some of the more 'professional' ones, they have multi-stages that drop off. lookup this user, he has 2 and i think a 3 stage bottle rocket: gk123434534
