Water rockets work exactly like their big brothers at NASA. A reaction mass is forced out of a vessel with pressurized gas, sending the payload into the air. In this case, the pressure vessel is a ...

Water rockets are like their model rocket cousins, except that these are powered by a combination of water and air pressure instead of a chemical propellant. The pressure vessel, the engine of the ...

Water rockets are plenty of fun, but they can be even more fun if you go wild with the engineering. [The Q] is one such experimenter, who built a dual-thrust water rocket that even has a parachute ...

When used as a rocket booster, it is filled with 66 Ibs. of water heated electrically to 504° F. The water cannot boil because it is confined, but its pressure rises to 50 atmospheres (735 Ibs ...

In today's video I want to show you how to build a powerful dual thrust rocket with a tomy timer and parachute. Materials you need: 1.5L coca cola bottles (because it can handle high pressure), nut ...

The 4M 4605 Water Rocket Kit can fly up to 90 feet in the air using only water pressure. The final word on the best model rocket kits Science toys are some of the most entertaining for kids.

The Idaho State University Physics Department hosted their annual water rocket festival in Tydeman Park this weekend.

The nozzle would be protected by running water. A Nuclear Salt Polyethene Rocket might achieve 8.19% of light speed and could have better safety characteristics. The nuclear salt water rocket is one ...

Primary school children investigate the theory behind what makes the Bloodhound Supersonic car's rocket engine work, trying to make their water rockets travel the farthest.
