12 gram co2 discharger
thingiverse
Made this for airsoft grenade it just makes a loud noise if you toss it in a gatorade bottle and close the lid. Instructions parts needed are a 1\2 inch nail and some pvc cement for the plug which must be trimmed flush afterwards. p.s. this thing is potentially dangerous, as all things are if misused so where gloves and eye protection. And for heavens sake use common sense.
