How it works
How it works
this is my catapult
This is the lever as labeled. It is powered by the rubber bands.
I am using a large screw for the wheel and axel.
The rubber bands create a force that when release launched around 100.ft.
The black thing is some rubber tubing that I found around my house.
The lever you pull back and when you let go the force from the rubber bands push the lever forward witch causes the marble to launch.
