I've designed a BallBusting machine that is simple, powerful and you can make it with parts that you may have, or any hardware store stocks.
This machine is adjustable to give as hard a smack to your ballz as you can stand. Or as lite as you want.



What you need;
1 hinge
2 rollers
loop bungee cords
1 foot 2X4 with 1" channel on bottom for rope to run thru
2'X2' base
rope
heavy duty hose
a few screws


Just squat over this with ballz hanging, pull the rope and let go of the rope. This thing can really make your ballz fly.
Or, sit in chair, put this machine in front of you, pull rope, let go, and smash your ballz thata way.

Any questions?
