What is inside a baseball bat?

Answer 1

A "Baseball Bat," it used in a sport called, Baseball. What it is, is either a wooden, or aluminum bat, ranging from 20" -sometimes 40". It is used to hit the ball that is pitched down the plate, you swing it with your arms, and the ball will bounce of the bat. There are rules though. If you end up putting a cork in your bat, (which makes the ball bounce off the bat harder) and if they find out, you could get suspended, or even kicked out of the Baseball league.

Answer 2

Wood bats are solid...wood. Aluminum and composite bats are hollow.
