Thrust structures.

Today Sam and I made a thrust structure that would servive three "falls". To test this you would put the structure on a piece of wood, drop a sand bag on the other side of the wood, and then the structure would fly up. There was a bottle balanced on the structure and you had to make it go high enough so the bottle would fly off the pole it was on. Sam and I built a triangular one. We had to build it out of popsicle sticks. Then we tried building it out of wooden scewers. We used the same design for both of them and both worked.

This has to do with Newton's third law because for every action there is an equal and opposite reaction. When the sand bag came down, the structure went up! I'm not really sure how this has to do with mission to mars. I think we will be aplying Newton's third law in some way.
