After finishing our catapult, we were wondering how we were going to launch it from a high place. I had no ledge or little crevice in the wall big enough to fit our catapult. So we decided as a group to tape a slab of wood to the wall, and have it sit on top of that. Let me just tell you, that was much harder than expected. Audrey had to leave right when we established that, so there was just Julia and Julia left. With one person holding, and the other one taping, we had a pretty good process. But it took a lot of tape. It looked messy, but that wasn’t the problem. When we tested it with the catapult (which had two full soda cans and a metal fork), and it sagged down. So, after putting our heads together, we took a piece of string and taped one end to the wood. The other end we taped to the wall, and stretched it tight like a guitar string. It seemed to work well. After we repeated that on the other side, we peeled of the excess tape. Julia’s mom arrived and it was time for her to leave, so we took a quick picture of our catapult holder to submit to Mrs. Edwards. The next morning when I had woken up and checked on it, I found the catapult on the cushion we had put beneath it to stand on. The slab of wood was hanging from a single piece of tape. We probably shouldn’t have left the catapult on the stand overnight! Back to the drawing board!
