Sorry to brake it to you, but that was sarcasm. As a future tip, don't post stuff that knex has already designed. Post original stuff you came up with. You will be alot more popular that way. But good job on your second ible anyway.

How high does the ball bounce?

colton blake (author)DJ Radio2010-06-04

Pretty high I guess. If you bounce it hard enough.

What if you just drop the ball? Yes, I know that sounds wrong, I don't care.
