Batter up! Find the sweet spot and hit a homer!

Materials Needed

  • wooden baseball bat
  • hammer
  • sticker or piece of masking tape



  1. Baseball players try to hit a baseball on the sweet spot of the bat, because it can make the ball go really far.
  2. To find the sweet spot on your baseball bat, hold the bat loosely between your thumb and fingers so that it is hanging down toward the ground.
  3. Have a friend hit the bat with a hammer every inch or so starting from the middle and working her way down the bat.
  4. If you're holding the bat, you will feel vibrations traveling up the bat to your fingers when the hammer hits the bat.
  5. When the hammer gets to the sweet spot, you won't feel vibrations. Does the hammer make a different sound when it gets there? Mark the sweet spot with a sticker or a piece of tape.

Ready for the science scoop? When you hit the bat with the hammer, it pushes the bat sideways a little, but it also makes the bat bend. The bat bends so little that you can't see it. But it bends and unbends really fast - so fast that you can feel it all the way up to your hand. If you hit the bat at the sweet spot, the hammer still pushes the bat sideways a little bit, but the bat doesn't bend much, so you don't feel any vibrations in your hand. Because you don't waste any energy on vibrations, you can transfer more energy to the ball. Does an aluminum bat have a sweet spot too? How 'bout a plastic one? A broom handle? Try it out, and be sure to write and tell us what you found.

Bethany, age 12 of Spicer, MN wrote:
It worked when I did it with a wooden bat, but not when I used an aluminum bat. I think it didn't work becuse aluminum doesn't bend as much as wood.
