Inspired by my childhood interest in building blocks and Legos, the Adjustable Marble Roller Coaster has romovable cubes that can be use to build variable height support towers on which to attach the plastic marble runs. This toy will allow children to learn indirectly about the concepts of momentum and gravity as they build various sized valleys and hills within the marble run and see if the marble completes the roller coaster.

The Adjustable Marble Roller Coaster will allow for hours of both individual and group enjoyment amongst youngsters as they experiment with the toys and challenge each other to little competitions. The parts will be made out of durable, high impact plastic which will be safe for the children to use. This toy should be used by children over the age of 5.
