Water Rocket Launcher: Unique grip & release mechanism.

Introducing a unique release mechanism for water rockets. It works on the principle of expanding a flexible tube to grip the bottle from the inside of its neck. This also forms a perfect seal, eliminating the need for o-rings seals. The seal is much more durable than o-rings as well and should withstand the abuse when being used by kids. The mechanism is fairly simple to make and uses readily available irrigation fittings. A complete explanation of how the mechanism works and how to build it yourself is given. The video concludes with a number of test launches, shot in "real time" as it was tried out.
