Superman Tennis Ball Cannon
Tuesday, April 5th, 2011 – running time 03:50
Taking the same basic idea behind a spud gun, we can make it smaller and more portable and launch tennis balls instead of vegetables.
In order to pull this off you will need to find some strong tubing that will tightly hold a tennis ball. I used a defunct leaf blower tube.
Place your tube into a strong base and form a seal using duct tape. Make sure to wrap the tape around several times to create a very strong seal, we do not want air escaping.
The fuel we used was about a second worth of hair spray. Once the fuel is added you should shake the tube for 20 seconds and make sure everything inside is vaporized.
To ignite the fuel source you can take apart a BBQ lighter and remove the piezoelectric igniter inside. Take the two wires attached and place them into the tube, when the button is pushed the fuel will ignite.
