This change we are going to make a catapult. We have to make a block go at least a foot. You get 3 try's and need to get a 66% success rate.
We have made the catapult. But the bottom is unstable. And it won't catapult the block far enough. So I am going to make the beam longer so the block will go a foot. I will also add more to the bottom to make it stable. I hope I can finish it today.
I added the wheels so it would stay on the ground better. I got a 66% success rate. In my opinion is good. But if the beam had a little bit more support than I would have gotten an 100% success rate.
