To make hills, lay the track over a stack of books.
The track can be suspended in a configuration of your own design
using any rod stands with half-inch diameter rods to which the track
can be clamped.
CAR ASSEMBLY OPTIONS
1. Wheel Labels
Labels which simulate the look of a wheel are supplied for the user to
apply to the flat circles on the car body.
2. Bumper (elastic and inelastic)
The bumper can be attached to the car with a thumb screw through the
hole in the center of the car (See Figures 7a and 7b).
a) Orient the bumper so the circular indentation in it is up and it is
aligned with the car's circular mass tray.
b) To make an elastic bumper, small rubber bands are supplied with
the bumper. Stretch a rubber band across the bottom of the two prongs
on the bumper. For high speed collisions, it is necessary to double
over the rubber band to make the rubber band stiffer.
For completely inelastic collisions, remove the rubber band and put a
small amount of clay in the "V" slot on the bumper. (See Figure 8).
c) Masses can be added to the car with the bumper attached by
inserting a screw up from the bottom of the car through the threaded
hole in the bumper's mass tray. The masses fit over the threaded screw
