Rube Goldberg Project 30 point project

What is a Rube Goldberg? a contraption, invention, device or apparatus that is deliberately over-engineered or overdone to perform a very simple task in a very complicated fashion a chain reaction.

Some Ideas Drop a marble down a paper towel tube so that it knocks over a chain of cereal boxes and batteries, too. Set up a pulley system using a piece of string, two plastic cups, a milk jug filled with water, and a weight such as a battery. Roll a piece of aluminum foil into a ball and tie a piece of string around it. Tie the other end of the string to a chair or other object. Pull the ball backward and release it so it bumps into a soup can. You can set up the soup can to roll into a chain of cereal boxes. Set a half-full water bottle near the edge of the table so that it pours into a funnel when the water bottle is knocked over. Place a plant underneath the funnel to create a watering mechanism.
