Let me explain the machine is not only a concept but also reinvention of past technology to accomplish a new task . In our chain reaction machine, we have the Arduino controller to power a motor that moves a candle next to a string. The candle burns the string that lets the weights on the other side to pull down letting the bicycle air pump release air. The air travels through a tube, into pneumatic cylinder that pushes into a nerf gun trigger. The nerf gun shoots a dart that hits a paddle ball. The vibrations send a metal marble down a green track then drops into a red funnel. From the funnel the marble lands into a train's smoke stack completing the circuit to powers the train, which is holding a red bull, forward on a track. Then the train will hit a momentary button that triggers a recycled Ford electric lock cylinder that pushes the red bull can off the train. The can then rolls down a PVC pipe and lands in to the open hand of the person waiting for the red bull.
