How do you hunt rabbits with THAT?! Do you launch the rabbits AT the ball bearings?! ;-)

Actually, they use these things to launch rolled up free T-shirts into the crowd at our Colorado Avalanche hockey games. Quite potent - they can easily hit the upper part of the second deck. They have some compressed gas cannon they use to hit the third deck nosebeed section. If you got blindsided by one of those slingshot'ed or cannon'ed T-shirts they'd probably knock you right off your deck.
