Week 2 balloon rocket

In week 2 the experiment was to create a balloon rocket. We did this by tying a piece of string between 2 chairs, threading a straw through the string, and then taping a balloon to the straw. We blew the balloon up and wa-la!
The balloon made it to the end two out of three times with half of the air remaining in the balloon I think the drag was very strong because because it didn't go fast it just spun! The distance the balloon traveled is 5m, it got to the end in 1.68 seconds I wonder if the more it spins the slower it goes! I think I'm in the same place on the rubric.
