Marble Over the Wall

  • Marble Over the Wall
    Design and Drawing for Production

    OBJECTIVE:  To get a standard sized marble over a wall and into a target on the other side


    • You cannot touch the marble with your hand
    • Your project cannot touch the wall during the processes
    • Your hand cannot simulate “LIFTING” in any way
    • The marble must be brought up from the base and sent OVER the wall, not around the side.  Marble will start within 2” from the base.
    • Your project can hang over the wall by 3 inches, but cannot drop down towards the target
    • The project must be able to sit by itself without your support of holding it
