In high school we built catapults for Physics class that needed to hurl a tennis ball 25m exactly. We used the bands from a slingshot and 2×4’s. My team took first place of all the entries. Later on during college, my dad gave me the trigger — all that was left of the rig when he scrapped it.
Holy Cow! I’m on MAKE!
Thank you so much!
