1) i am not using pvc to hold the pressurized air, i am using the type of air tanks that we got in the kit this year.

and i think that i might perhaps cut the "barrel" part of the gun down because one tank full of air causes the potato to go 2/3rds of the way through the barrel so i think i will add the second tank and maybe it will work then.

also, the tip on how to make an air tight seal really helped, thanks.
