Week 2, balloon rocket!
For week 2 we did the balloon rocket with straws,string/wool and we expanded to try and use no straws. It went pretty good because we rolled up paper into a straw shape and then we used it and it worked! The forces that were on the balloon were a push and pull force.What I learned during that was that you don't need the same thing to do it. I am still on multistructural.
