The project that I did was the Ruth Goldberg project. Our plan was to make the car go and hit the dominos and the domino falls to a parashute that will have a thmbtack in the bottom, and hit the balloon and pop.We tried to do the parashute, but the parashute didn`t go the way we wanted, so the next week Soyoun came to my house and we had a great idea, but we didn`t have the materials. So I went to Soyoun`s house to bulid it and we brought it to school the next day. I learned that the machine dosen`t work always the way you want. The fun part was we can make a machine.
