Pea Gun!
thingiverse
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.
