Joseph Wilding's Water Rocket Launcher
contact: wilding@austin.rr.com
I designed the following water bottle rocket launcher in 2004 based on design
ideas from Ian Clark and Michael Powell. I modified the design slightly in August
2005 to be more stable.

The launch mechanism can be easily removed from the base to insert into a bottle rocket. Then placed back in the
base to pressurize and launch the rocket. The base can be rotated and tilted to achieve optimal launch (into the wind)
and will remain stable even when tilted up to 20 degrees.
Caution: A water bottle rocket can become a dangerous projectile reaching speeds of over 65 mph and should never
be pressurized or launched horizontally. Never point a pressurized bottle at a person or animal. Never stand directly
over a pressurized bottle.

The secret to getting a water/air tight seal on the inside of the bottle neck is the use of two o-rings on the
launch tube. I have a friend with a lathe (metal not wood) in his garage where I make my launch tubes.
However, if you are careful, the groves can be successfully cut using a hacksaw blade and a wood lathe on
a slow speed. The cpvc insert is to give the launch tube enough thickness to be sturdy after the o-ring
grooves are cut.

October 2005 I designed my own fin pattern
