Pea Gun!

This is a 'gun' that I made to shoot peas, but the barrels diameter is 10mm, so you could shoot anything smaller that that.

All you need is 2 soda bottles, a solenoid valve and a 3D printer.

You can choose from a variety of different handles, with 1 or 2 bottles. (The 'double handle' is untested)

I pressurised it using either the valve from a foot/soccer ball or a bicycle, the bicycle valve worked best.

Enjoy!
