jakey0p teaches you how to make a mini potato cannon. You start off with a piece of Tide to go. You will only need the orange part of it so take out or simply cut the white plastic parts. Cut the back of the orange tube and attach the cap which fits in there. Put two thumb tacks through the middle of the orange tube. Now you will want to use the element that makes a spark from a lighter, from example. Cover the wires on the outside using duct tape and make sure the sparks are on the inside. Add hairspray and put the cap back on. Then use the sparker to build explosive pressure and make a piece of paper or a small piece of potato fly out the front tube.
