Can I make anything cool out of this?

I need something to do on some boring days

a while back I was really ino making potatoe guns all the parts you could get at home depot, I never wanted to spend that much on the gun to go to propane, I used different propellents, I found Right Guard and the orange engine degreaser (the active ingredient is similar to gun powder) to be my favs) I had one model that the 2nd half of the barrel was chocked down to accpect a small red potatoe, and since the projectile is smaller and increased the compression it improved the performance. The key was not to put too much propellent in the combustion chamber you wanted to get the ratio in a happy zone and I used a BBQ lighter for ignition.
I brought one to work one time and I got a bunch of guys into it and they wernt the most mechanical of people so I would make them for a price. I have seen some crazy designs on the net, you can also make rockets out of PVC pipe fo rthem
