There is a book (I believe it is called "the method of Motion", email me
personally, and I will find the exact title) which describes a "drip" car.
You use a soap bottle to drip colored water out at equal time intervals. I
forget what causes the acceleration (could be a wind up mechanism), but by
measuring the distance between the drops, you get a really good way to
measure accelleration. Anyway, the whole thing is done very simply.
