How To Build A Cannon That Shoots Wiffle Balls At 50MPH [Video]

Repurpose your leaf blower into a pitching machine

Chances are, your leaf blower is collecting dust in a garage right now--and it will until this fall. So rescue that yard-clearing device for a far nobler purpose: blasting lightweight projectiles at top speed.

Channeling the air from the leaf blower through a simple assembly of PVC pipes turns it into a Wiffle ball pitcher. It can also hurl foam balls and even water balloons and snowballs, although heavier projectiles should be avoided.
