Simple Machines

We were invited to go into Room 1 on Friday to have a look at the machines they had made. Room 1 had been looking at "Rube Goldberg Machines"... A Rube Goldberg machine is a contraption, or invention that is deliberately over-engineered to perform a very simple task in a very complicated fashion, usually including a chain reaction. You could  click here to take a look at an incredible machine on you tube. Room 1 children had made a few smaller versions. Most of them rang a bell at the end of the chain reaction.
