The first thing that should be done is to build a base for the roller coaster track. A flat wood is fine. The pvc pipes will then be attached to the wood board using duct tapes.
It should be remembered that the first pipe’s other end has to be elevated. This will permit the marble to have enough elevation to roll. Upon laying the first pipe, the other end can be attached with rubber tubing for the loops. Depending on the preference of the builder, he determines the number of loops that single rubbing tubing can have.
In order to test the efficiency of the loops, the builder can first create a single loop to determine its effect on motion. If the motion is weak, he can add another loop on the same rubber tubing. The more loop it has, the faster the marble rolls. Also, he may cut several pieces of rubber tubing for subsequent loops in various levels of the track. After the first rubber tubing is attached to the first pipe, another pipe can be attached to the rubber tubing to complete another track and so on.
The wood board can be attached with different objects of elevations that can serve as mountains for curved tracks. Blocks or small boxes will do. Rubber tubing can be held by circulating these artificial mountains for curved pathways. Upon completion, the marble will then be inserted in the elevated first pvc pipe.
The marble will then have a rolling downward effect continuing to the other side of the pipe which is attached to loop rubber tubing.It will then roll inside the tubing in loops, giving it more energy to continue its trajectory. The marble will then pass to a straight pvc pipe directly parallel to the wood board. Because of stored motion, it will pass through another loop which will generate some more energy. Afterwards, it will go through the curved rubber tubing beside the artificially created mountain side. This will continue to role up to the last pipe at the other edge of the board.
