Kinetic Energy Challenge (MARBLE MAZE) Kinetic Energy Challenge (MARBLE MAZE) You and a partner are to design and build a marble maze that relies specifically gravity to pull the marble through the maze. Your maze will be timed with a stopwatch, from the second that you release the marble at the top of the track exactly 1 meter above the ground, until it comes to the end of the maze. You should aim for your Marble to take exactly 1 minute to complete it's course. You may put as many curves, twist, trick ramps and even reverse ramps as you can.
