A piece of tape pressed against a sample of molybdenum sulfide will peel off layers of the sample. Additional tape can be used to cleave the peeled sample hundreds of times.
A cast iron bomb is completely filled with ice water, then placed into a dry-ice/acetone slush and covered with a wooden box. When the water in the bomb freezes, the cast iron bomb explodes, breaking into several pieces, and destroying the box in which it was placed.
The flow of four different liquids from four pipets is started simultaneously to test their viscosity.
Four funnels are connected to differing lengths of capillary tubing. The greater the length of the capillary tube, the longer it takes for the water to flow through the apparatus.
This is an introductory movie showing, in wider angle, the manner in which the experiment for measuring relative viscosity is performed.
