How Do You Build A Potato Launcher?
Everyone loves to eat potatoes, but firing them out of a cannon can be just as fulfilling. Also known as a spudzooka, potato gun, potato cannon and Spud Gun, this is a fun project that demonstrates the principles of physics. Part of the thrill and enjoyment of constructing a potato gun is to experiment with the basic design to tweak performance and learn valuable engineering lessons. Here’s how to build your own potato launcher • Create the air chamber. Cut two lengths of 2″-diameter pipe 30″ long and a third 6″ long. On the end of one, glue on the 2″x1″ SPIGOT x FIPT reducer bushing. To do this, glue the bushing into the coupling, then glue the coupling onto the pipe. Using the elbows, then make a U-shaped pipe, with the 6″ section as the bottom of the U. Cut the bike tube off of the valve, leaving the valve and a small flap of rubber around then the valve, about 3/4″ wide. Before gluing on the pipe end cap, drill a hole in the center of the cap just big enough for the bike valve. Ins
