    i was watching myth busters and it said a cork in the middle of a baseball bat would make it less efficient because the cork absorbs energy. Then it got me thinking, if you had a multi layered bat, starting with wood, and the layers got harder and harder, would it be much more efficient, caus eit would be repelling much more energy?

    Don't beleive everything you see on TV, even on Mythbusters.

    Did anyone bother to define the efficiency of a baseball bat ? I have no idea what that is supposed to mean.

    But a corked bat can be swung faster and some major leaguers have been know to cheat and use them for just that reason. They have also been known to use weighted "fungo" bats for some purposes.

    There is a tradeoff between mass and speed in optimizing a bat for momentum. A bat that is either too light or too heavy will not hit a ball as far as one that is just right. And "just right" is dependent on the batter, his strength and his size.

    Just right depends on the pitch too. A good pitcher has wide range of speed, masked by deceptive throws. It's a guessing game that way.

    For clarification purposes:

    Quote Originally Posted by http://mythbustersresults.com/episode83
    This myth operates under the assumption that cork-filled bats can be swung faster because of their lighter weight, and that the springiness of the cork could propel the ball farther. To eliminate the human factor of the myth, Adam and Jamie constructed a special batting rig and used a pressurized air cannon to launch the baseball at it. Tests showed that the cannon could launch the ball 80 miles per hour, which is the average speed of most MLB pitches. Regulation bats could propel the ball away at 80mph while corked bats could only propel the ball 40mph, half the speed of regulation bats. The reason was because cork bats have less mass to transfer force into the ball, and the cork actually absorbs some of the ballís impact. The Mythbusters concluded that using a cork filled bat will not improve your performance (it will in fact hurt it), and the major league batters who were caught using cork-filled bats risked their careers for nothing.

    you mean we shouldn't trust half a dozen actors specialising in special effects to correctly portray scientific information? I'm shocked!






    (I would like to take this space to apologise, jame and adam rock!)

    All in all, I think the Mythbusters do a good job testing things fairly scientifically. All the details may not make it to air, but you can see some of what got cut on the website. The only thing is, sometimes they define the target very narrowly, which I suppose makes good TV, but it leads to a lot more busts that some people might disagree with.

    I assume it means which bat will hit the ball further given the same speed of pitch and swing, but I didn't see the episode so I can't say for certain.

    That's a good point, but in that case shouldn't they put the cork at the ends of the bat where the ball doesn't hit? I don't know if mythbusters tried that, but it would be interesting to see the results.
