Brenden's Simple Machine experiment

Brenden had a "Simple Machines" science project in school a few weeks ago. They worked on their project for weeks. They changed it up many times but finally were satisfied with the results. The project had to have three exchanges. Their project was a car rolled down a ramp, hit a marble, which hit dominoes, which hit something else causing a cookie to fall out and fall down into a carton of milk. Their run through was great but during parent time they ran into some trouble. It did however work for the other shows which is important. Brenden likes to experiment and was proud of his project. He is a good student and works hard but doesn't like it when things don't work like they are suppose to. He was a good sport though.
