We have homemade water clocks for our Galileo inclined plane expt.
It consist of a bucket of water with tubing coming out of the bottom
and an eye-dropper orifice at the end of the tube. The water is
collected in a graduated cylinder. The markings on the cylinder tell
you the time (they must of course be calibrated against a real
clock). -- Wolfgang
