CO2 Rocket

!!! BE SAFE - CO2 AND HIGH PRESSURE CAN BE VERY DANGEROUS !!!
!!! ATTEMPT AT YOUR OWN RISK !!!

This is a CO2 cartridge rocket.
You will need :
-co2 cartridge (used in airsoft like the 12g umarex)
-a 40mm PVC Pipe (2 or 3 mm thick, print the rocket model accordingly, the 2mm version has a looser fit than the 3mm version).
-A 2mm nail.
-Small diameter (1 mm or less) metal wire

Place the fins in the right position, the leading edge should point up when deployed.
Attach with small metal wire (glue or simply bend the wire to hold it in place)

Attach the nail to the en cap
Attach the cap to the pvc pipe

Load a CO2 cartridge in the rocket.
Hold the tube at a 45 to 70 degree angle
Drop the rocket in the tube, the nail should puncture the cartridge's valve and the rocket should fly out.

BE VERY CAREFULL, CO2 IS VERY HIGH PRESSURE.
THERE IS AN EXPLOSION RISK.
TRY THIS PROJECT AT YOUR OWN RISK

To prevent this, test everything before firing, be sure the rocket slides
