1. Safety instructions
The Communicating Tubes apparatus is made of
glass. There is a risk of breakage and therefore of

• Handle the glass vessel carefully
• Avoid an exertion of mechanical loads on the
apparatus.
• Be careful when using coloured water not to
let it splash on your clothes, for example.
2. Description
The apparatus Communicating Tubes is used for
demonstrating levels of liquid in linked tubes.
It consists of four differently shaped glass tubes
that are open at the tops and are connected together, the whole apparatus being mounted on a
base.
3. Technical data
Height: 195 mm approx.
4. Operation
It is practical to use coloured water during the
experiments. Recommended colouring dye:

• Slowly fill the large glass cylinder to a level of
about 2/3 with water. During this, observe the
water levels in the four tubes.
• As a demonstration, tilt the apparatus toward
either side and check the water level again in
each case.
