How to Easily make a potato cannon
To make a potato cannon you will need PVC piping, PVC glue and a lighter. First, apply the PVC glue to the inner rim of the gas chamber and fix the combustion chamber to it. Screw both caps onto each end of the PVC piping to seal the chamber. Take one of the lids and drill a hole big enough to fit a lighter through it. Glue a one-meter long PVC pipe to the combustion chamber. Next, take a round piece of fruit or vegetable and load it into the cannon. Light the combustion chamber and the object will fly out of the cannon.
