In D.T.F lately we have being making Rube Goldberg machines. They are a series of complicated chain reactions to do one simple task. This picture is an example. In my group were Harriett, Prudence, Samantha and me.

My group’s machine has four different simple machines because one of the rules were that you had to have the same amount of simple machines as the people in your group. My simple machines were an inclined plane (a ramp), a lever, wheels and axles. Our group machine is attempting to smash a jar of lollies.Though we haven’t finished the task yet, our machines are looking great!
