WORLD RECORD Water Rocket Car 0 - 343.5 kph in 2.5 sec

Rocket car 15,000 Hp 343.5km/h in 2.5 sec WORLD RECORD Powered by an 'overheated' water rocket. Water is heated to 260 C in a pressure vessel which generates 60 Bar (over 900 psi) of pressure. The superheated water flashes to steam when released through a rocket nozzle to atmospheric pressure. The rocket uses 110 liters to do 80 meters and produces 15,000 hp.

Water Rocket flies to 1752 feet (534m)
This is a highlights video of our high pressure water rocket called Dark Shadow flown at "Thunda Down Under" in Westmar, Queensland on 13th and 15th March 2015. The video shows the 3 flights flown over that weekend as we progressively increased the pressure.

How To Make a Huge Water Rocket by Splicing Bottles Together!
Make huge water rockets by joining multiple bottles together using this tutorial. If you want to see the Webpage version of this tutorial, please visit: al.htm This tutorial shows you how to join multiple bottles together to make a Huge Water Rocket using our Slip Joint Splicing Technique. This easy new method of joining bottles creates strong and attractive joints by reducing unnecessary and/or detrimental steps from the traditional splicing techniques commonly used. Our testing shows these splices typically hold past the point where the other areas of the bottles become permanently damaged from the plastic stretching (which varies with different size bottles). On 500ml bottles, we have seen 195PSI sustained with this method.
