Rube Goldberg 3
Today, Leo and I collected the materials we need for our Rube Goldberg machine. We needed: a ball, a goal (box), some string, duct tape, a toy car, toy car track, a marble tube, a marble, a pulley, a soda can, dominoes, a shoe, paper, and a nerf dart. It took about an hour to find everything we needed. After that we tested everything separately so we could make sure that they worked. Then we ran out of time because Leo had to leave.
Overall, today we finished all the things that are due on the 18th, and Leo and I were very successful.
