Product Description

Action Science and Fun Project Possible From HHO Gas

Build a hydrogen powered pistol that fires a 30 caliber projectile at a moderate velocity…purposely kept down as this could easily be classified as a dangerous firearm using water! The actual pistol section is built from materials available from hardware stores. The design as shown was done by one of our more creative technicians. The design of the actual barrel, chamber and firing mechanism must be followed but that of the remaining assembly can be at the builder's discretion. Plans include photos, schematics, and drawings to complete this fascinating and fun project. Materials for the actual device are readily available. Easily punctures metal/steel cans.

These are downloadable plans (also available as paper plans), requiring parts and assembly.


Now at last the ultimate all action science project using only “harmless” water for the energy source!

This project can be dangerous and is intended to be supervised by qualified school, university or adult personnel. The blast effects can cause damage and injury.

Unfortunately we have no control on the amounts of the gases used, on the blast containers, nor can we enforce our safety recommendations. We therefore can only warn the experimenter to use the small amounts as shown in plastic baggies, and treat the kinetic devices with the respect you would give real weapons. The experimenter must also be aware of the fact that this is the most efficient form of released chemical energy per given weight of any explosive or fuel. Hydrogen when mixed with oxygen must be treated with the precautions of an explosive -- it is a highly potent form of energy and must be handled with caution at all times.
