I hope you have enjoyed my blog reflections on my Rube Goldberg machine! Vrinda and I have finished the contraption and it works! We changed our design to a fully functional chain of reactions. First, a baseball puts more weight on one side of a large piece of foam than the other, causing a tennis ball to roll off the foam and down a ramp. Then, the tennis ball hits a Jenga tower with a ball on top, attached to the ceiling by a string. When the Jenga tower falls, the ball travels toward where the string attaches it to the ceiling, but hits a book along the way. The book hits more books, acting as Dominos. When the last book falls, it pushes a toy train forward and down a train track ramp. The train then hits a toy car, which travels around a loop when pushed forward. The car hits a power switch, letting electricity flow and charge my phone. It took hours of work and endless amounts of effort, but we finally made our Rube Goldberg machine!
