Fascinating facts about the invention
of JD Batball by Jacob Dunnack in 2000.

The toy invented by a kid, for kids!

"I called it a Batball because I can store my baseballs inside the bat and I like it. It's really cool.'' says Jacob Dunnack.

Have you ever had a problem with something and wished there was a good solution to fix it?  Two years ago, Jacob Dunnack (then age 6), had a problem. He forgot to bring his baseball when he brought his bat to his grandma's house to play baseball.  Needless to say, he was disappointed, because he couldn't play baseball without the ball!  But Jacob didn't let that stop him.  He not only wished there was a good solution, he actually invented one: the JD Batball!  Jacob first introduced his invention at his school's "Invention Convention."

The JD Batball is a plastic baseball bat with a removable cap so one can store the balls inside so the balls won't get lost.  This handy invention helps kids can carry their bat and balls with one hand, while never worrying about forgetting or losing their baseballs again!

What makes Jacob's story even more special is that he was born with a congenital heart defect (two major arteries were crisscrossed).  He suffered a stroke during an operation when he was just a baby, and the doctors thought would leave him blind and paralyzed.  But Jacob proved them wrong!  Though he has limited vision and limited use of his right arm, that hasn't stopped Jacob from living a normal life...and being one of the few kids who has actually gotten his invention on toy store shelves!   The Batball is a patent pending product. Invented in 2000 by 6-year-old Jacob Dunnack.
