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.
Well ok then thanks for the good feelings on my second instructable. :(
Im not being mean, I am being helpful by giving constructive criticizm. I am sorry if I came off mean at first. No hard feeling meant.
How high does the ball bounce?
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.
