Adhesion Disc - GS-365

Adhesion Disc.

This glass disc with a smooth ground edge is used to show the great adhesive force of water (or other liquids).

The unit is suspended from a sensitive spring balance (not included) with the disc just resting flat on the surface of the liquid. When an attempt is made to lift the disc from the liquid surface, the force required will be seen to be greater than just the weight of the apparatus. The disc is suspended by a single thread which passes through three small eyes. These threads are deliberately twisted to provide enough friction so that the disc may readily be made to hang in a level position.

Wabash #GS-365.

Disc: diameter = Θ7.5cm.
