glass. There is a risk of breakage and therefore of
injury!
• 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 to-
gether, the whole apparatus being mounted on a
base.

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.
