Aidan D. Energy Transfer Machine
I created the water alarm. It uses wind, potential, kinetic, and electrical energy (2 AA batteries) to sound an alarm. The transfer begins when an oscillating fan (Section 1) blows a paper plate, slightly lifting a track that a ball bearing is resting on (Section 2). The ball bearing rolls down the track, through a tube, and hits a book (Section 3). The book falls over, creating wind energy that topples another tube (Section 4), which falls into a cylinder with a toothpick and wire attached (Section 5). When the cylinder is knocked off its perch, the wire releases from the toothpick, falls into a cup of water connected to an alarm circuit (Section 6), and completes the circuit. Electricity from the battery sounds the alarm once the circuit is complete.
