2B20.20 Dropping Plate

Pressure holds a glass plate on the bottom of a glass tube inserted into a beaker of water until the pressure is equalized by another fluid poured into the tube.

This photo shows a large glass vase full of water. A glass tube, originally open at both ends, is partially submerged in the water. Water pressure holds a square glass plate against the bottom of the tube. A small beaker of water sits on the table near the vase.
