No, we weren't ignoring anything. We had real live hotwheel cars, real live 
track, a piece of tape holding the track to the wall. You calculated where 
to start the car, and if it went around without falling off, you were done.

Of course, before you started, you made some measurements like how far the 
car rolled straight given different starting heights. The strobe 
lights/cameras helped too.

We did similar things with dart guns and a couple other experiments.
