Five year old "mom, come see what I did to the car tracks". I go into his room and the little designer had reassembled the tracks so the loop-the-loop was attached to the high spped launcher, the 4-in-1 race track reduced to a single car that was launched off a ramp into space at the end, the window sill ramp (previosly attached to the loop-the-loop) was redesigned to have a launching ramp at the end. "Great designs buddy!" We sat down and did an optimation experiemnt of which cars did best on which tracks to declare a winner.
