Unscrew the cap on the bottle and insert a rubber stopper in its place. Feed the vinyl tubing into the hole in the top of the rubber stopper and use the clamp to clamp the tube on the same side as the opening of the bottle.
Turn the plastic upside down and insert it into the ring on the ring stand while putting the other end of the tubing into the beaker.
Fill the bottle with water up to the line you drew in Step 2 and add food coloring to color the water.
Loosen the clamp enough to allow a steady drip of water to run into the beaker while using your other hand to start timing with a stop watch. Use the wax pencil to mark the water level every 10 minutes.
Pour the water out of the beaker and into the plastic container that is positioned in the ring stand and repeat the drip process. Mark the water level every five minutes this time.

How did the Egyptians make water clocks?
It is interesting to note that the Egyptian water clock actually was invented by Ctesibius, of Greek origin. Because of the unique design of the water clock, it can be made to make sounds like some birds, chiming bells, and other various objects. The basic clock keeps time by allowing water to flow through a small orifice. The water flows from the holding chamber into the measuring bowl, which has markings on the side to denote hours. Some clocks included a float in the bowl that turned a wheel as the water level rose, showing the hours passed since the clock was started.
