This is our Rube Goldberg project.
Steps: a phone vibrates causing the ball to fall off and hit another ball, the ball then goes down a ramp and hits a stick that rotates and pushes another ball, that ball goes through a bottle lid, across a path of straws and falls into a bottle cap, the cap has a string attached which pulls a straw holding a ball and the ball goes down a ramp and hits dominos, the dominos fall into a path and ring a bell
Energy transfers: vibration to kinetic, kinetic to gravitational potential, potential to kinetic
