Building physics marble tracks-loop de loop track part 2 // Homemade Science with Bruce Yeany
After a review of physics marble tracks in part one, this segment gets into a review of the basic materials needed for building your own track by constructing a loop de loop track. In a future segment we will take a look a the physics of the loop de loop track by comparing the calculated measurements to the actual results found in the performance of the device.
the track is sold at local hardware stores or building supply stores as shelf bracket tracks
screws are #4 screws one half inch long
balls can be 1 inch steel balls, pool balls, golf balls or even large glass marbles
