long pvc pipe
combustion chamber( mixes the oxygen with fuel)
cap(the same size as your pvc pipe)
Step 1: Collecting the Parts
glue the combustion chamber to the long pipe with cement
Take a drill and drill a hole about the size of your lighter in the combustion chamber
Insert the lighter into the drilled hole and secure it by using silicone,ducttape,basicly anything that sticks!
Step 2: Shooting the Taters
open the cap at the end of your pipe
spray hairspray inside( 2-3 sec's)
secure the cap in the right way(you don't want it to hit your face when the gun fires)
aim at an angle of 45Â°
click the lighter and bombs away !!!
-- you can play paintball if you replace the potato with bath pearls
