When Pablo Panda Sandoval made history with 3 home runs in game one of the world series his head was probably buzzing. But when batters 1 in chilly 2 Detroit had the ball not quite right in the next couple of the nets, it will be their hands that buzzing. Ouch. Those hurting hands are caused by vibrations 4 in the bat after makes contacts with the ball and when captured on high speed video they can actually see the player's hands losing contact with the bat as they bends back and forth 5 at the speed of 6-700 times a second. Ouch but Penn's states Daniel Russell has a solution, a shock of absorber in the bat's knob that's tune 6 to cancel out the vibration 3 frequency that cause the most painful stings. He presented the analysis of this new shock of absorber on October 22nd at a meeting of acoustical 7 society of America. And thanks to a collaboration 8 with baseball bat maker 9 Marucci Sports, even if you can't hit the ball in the sweet spot like the Panda. Your hands may remain *.
