Launching From The Moon Lab

Today we did a lab where we had to get a balloon, and a straw up a length of fishing line. It was really hard, because in addition to the balloon we had to get a lot of different stuff, including a foam ball, paper towel tube and 2 wheels up the line, but not all at once. It was really difficult because the balloons didn't always push the stuff up the string, sometimes it just spun it around and around. I think that this was because we didn't hold the string tight enough.
