This term we did a rocket balloon with a fishing wire. It looked like the string was invisible because I couldn't see it when the balloon was going. The learning was how far it will go. I think with thinner string it would go further because there will be less friction. The forces we used were push and pull. I think the fishing wire helped it go further because it was a bit slipperier than the wool because the wool had bits of wool coming out from it. I am at multistructural for inferring and gathering data because I have many ideas.
