Our Design
Energy Transfers
Start:
Ball released by hand – pulls ramp off wall – tugs on a pulley – drops sand to activate see saw – raises marbles to make them go down series of ramps – hits dominoes – pushes last domino connected to water bottle – pulls domino to push ping pong ball – bounces and hits more weight to release golf ball – hits activator to set off the potentiometer connected to a battery and activated a fan – blows golf ball – pushes marble down a series of ramps and obstacles -pulls string – releases car down ramp – hits water bottle – pulls banner up as the final energy transfer.

The Construction Process

Wonderfully useless complexity! A joy to watch. How could you slow it down a bit to get closer to the minute mark?
The machine was a lot of fun to watch, so much going on. By removing the brigde at the beginning and changing the path of the next marble was genius! The slow potentiometer added a lot of drama to the run. But it was so disappointing at the end when the tiny car didn’t even budge the water bottle. Had that part been tested? Do you know why it failed? The bouncing ping-pong ball was very unique, I don’t think I’ve ever seen that before. Great job overall.
