fire away project

alliterations

at first, we started with a small arm but after testing we ended up finding a bigger piece of wood. We also started with smaller holes  but we drilled the hole bigger so there was less friction .

about our catapult.

we decided to build a long catapult instead of a short one. We did this so there is more force that can shoot the projectile farther and longer. we ended up finding out that 3 rubber band was the best amount of rubber bands. we used three because we found out with evedence that three rubber bands was the best amount

what we could improve on

we could've improved our communication,  we didn't really communicate to each other when we had a problems.

what we did well

 I think we did pretty well, we built the machine well and it went pretty far. it ended up going 40 meters which was pretty far for our class
