Things You'll Need
Instructions
Glue some spare Matchbox track to the plywood. The narrow edge of the board is the top and bottom, so glue the tracks running from the top to the bottom. Stick down the number of lanes you want to race with. The tracks should extend past the bottom slightly.
Lay out the stack of books at the head of your race track. Place the race ramp on top of the books so that it creates an angle.
Attach some additional Matchbox track, if you have some to spare and want to make a full track. You can also attach any stunt tracks that you have to the race track--to be fair, make sure there are the same number of stunts on both sides of the track.
Hold a ruler a few inches below the tops of the tracks.
Place all of the Matchbox cars behind the ruler at the top of the ramps. When ready to start the race, pull the ruler straight up to release the cars.
