Catapults

For the science fair my boys made catapults. I had very little to do with this project. The majority of it was done while I was in the states for my grandmother's funeral. Here are a few pictures of their stuff.



Jacob built an onager. I have no idea why it is called that. I just know that is what he is calling it. I know I could look it up, but I'll just let him explain it to me this afternoon after he finishes putting his board together.


He flung a cotton ball...


a rock...


and a marble. The marble flew the farthest. (These pictures weren't take during the actual experiment. His actual experiment pictures were blurry so we staged these.)


Will built a ballista.


He shot a pencil...


an unripe plum (they eat these here)...


and a marble. The pencil flew the farthest.

Again...I didn't participate in the catapult experiments other than to help type a few things. If I had been there I would have taken more pictures. Pictures that actually had someone in them. Oh well. Who wants to see kids when you can see catapults and flying debris?

Oh...and Brian never did get to shoot that flaming cotton ball he kept talking about. I think he is waiting until after the science fair is over so that there aren't burn marks on the wood.
