This video shows you how to make a powerful potato gun using 2 inch PVC pipe, PVC pipe adjusters and adapters, and an acetylene-propane torch. You secure all the pieces using PVC multipurpose cement, to ensure that your potato-gun doesn't break apart. The instructor lists all of the pieces you will need, then shows you (using many unnecessary swear words) how to assemble the potato gun in about 2 minutes. He tells you to make sure to twist each piece to thoroughly to distribute the glue. You then attach the acetylene torch, and use it to fire the potato into the stratosphere!
