Water Rocket Forum

So here is a video of my rocket design flying 254ft ~! ( as far as i know this is the highest single 2l bottle flight ever recorded )




And here is a simple yet really effective launcher to launch it with !!

Good Video.
But need proof.

How did you measure the altitude?

Also if you're going to be pumping up the rocket so close to it, you and your friends might want to consider wearing some eye protection in case of a rupture.
