How to make a homemade tennis ball mortar

*Note that I will not be held responsible to any damage to property or to the builder of this project.*

Parts:

1 3′ long 3″ diameter ABS pipe

1 3″ to 5″ reducer bushing

1 2′ long 5″ diameter ABS pipe

1 5″ diameter connector one side smooth and other side threaded

5″ diameter threaded cap

ABS cement

Well, this is pretty self-explanatory. It’s best to do a dry-fit. Insert the 3′ pipe into the smaller end of the reducer bushing. Insert the 2′ long pipe into the other end of the bushing. Place the smooth part of the connector on the other end of the 2′ long pipe. Screw on the cap. Once all dry fit is done, try to take everything apart and cement it, following the same directions.  Don’t forget to let glue dry before you launch a tennis ball!

Pictures coming!

    • It’s baiscally a Tennis Ball Cannon. You use hairspray in a combustion chan=mber thren you light it on fire wich does something called combusting and when the hairspray combusts it shoots the tennis ball or you can use a beer or coke can into the air about 200 feet.
