How to Put Tennis Balls in an Aluminum Bat

    Stand the bat on its handle. Make sure it is steady.

    Pry the flat-head screwdriver under the cap on top of the bat's barrel. It may take some muscle, but it will pop off. There will be a large popping sound as the pressurized barrel's air escapes.

    Push tennis balls down into the barrel. Depending on the size of the bat, three of four tennis balls will fit inside the barrel.

    Place the cap back on the bat and push it in until it is secure.


  • Use new tennis balls. They will have more bounce than old ones.


  • Make sure the cap is on tight; it could pop off with frequent use.
  • Almost all types of baseball and softball organizations, including high school and college leagues, forbid tampering with bats.

Things Needed

  • Flat-head screwdriver
