Create a Pythagoras cup 




Make one Pythagoras cup with available straw or tube.

Adjust the length of the intake tube

Measure the amount of water it discharges when the level goes higher than the top of the tube

Try with different size tubes and notice how the cup works

Think of interesting applications for the cup.

 Create a Water Clock using
Pythagoras cup principle


Make one working cup and calibrate with flowing tap water

Minute cup: Create a cup that takes between 1 to 5 minutes (depending on the size) to fill

Hour cup: One cup that takes between 20-60 minutes (depending on a cup)

Day bucket: It takes between 3 and 10 hours to fill (depending on size)

Adjust the tap flow

Calibrate and mark cups with a clock as a reference
