    Keep the marbles rolling with this fun marble roller coaster! It includes five yards of track, which not only features parallel running rails so you can constantly observe the marbles racing along, but also includes a motorized elevator so you can drop a marble at the top, watch it race to the bottom, and then have the elevator do the work of bringing it back to the top of the run to race again. Altogether, this set contains 200 pieces, including four marbles so you can start playing right away. An instruction manual gives tips on how to easily construct your coaster, but it is fun to use the pieces and come up with your own design. Elevator requires 2 "AA" batteries, which are not included. ~ Rachel

    Unlike other marble runs with solid plastic runways, the pieces in this set consist of two adjoined parallel running rails that the marbles cruise along. With this feature, you'll be able to keep an eye on your marble as it races along the track (which can be up to sixteen feet long). 132 pieces are contained in this set, including red track pieces, bases, structual connectors, suspension cable and two different types of marbles. ~ Megan
