Build the Track
- 1). Lay the two wooden planks parallel to each other along the particle board; put them about 3 inches apart. Glue them into place. The track is the space between the planks, and the planks will serve as barriers to hold the train on the track.
- 2). Glue a row of magnets, each with the same pole facing up, on one side of the interior of the track. It should take 36 magnets to cover the length of one side. Do not lay a magnet down on the track then lay another next to it with a different pole facing up.
- 3). Repeat Step 2 with the other side of the interior of the track. The magnets on this side should have the same pole facing up as the other side. Test the polarity by holding one face of a magnet to the face of a magnet you already glued down. If the magnets oppose each other, that is the face that must be upward.
Build the Train
- 1). Cut a styrofoam block down to size. It should be no more than 2.8 inches wide so that it can fit within the barriers along the track's sides.
- 2). Glue one magnet to each corner of the bottom of the train; this time the pole that faces down on the track should be the same as the one that faces up on the track. Test this by holding one of the magnets against the magnets on the track. If they oppose each other, that is the face that must point downward.
- 3). Allow all the glue to dry for at least 24 hours, then test the train. Set the train on the track and push it. It will glide smoothly along the track if all of the magnets are opposing each other.
