Launching From the Moon

Gemma, Le'Jayah, and I did the launching from the moon lab. At first we found it difficult to move the sticks and roll, but then we measured how many tiles the thing moved. It had moved 4 tiles with one balloon on and there were 16 tiles, so we needed to use 3 balloons. We tried it and it worked. After that we tried to move the ball and wheels with three balloons but one popped and we had to get more. Unfortunately that didn't work either. I wonder if It would have worked if we would have used four or five balloons or what wold have happened if we would have only used the wheels. One of us was recording the $ amount and the other two were building and blowing up balloons. This system worked very well. I think we spent about $300,000.
