Index of Refraction - disappearing glassware demonstration // Homemade Science with Bruce Yeany

The classic demonstration of making Pyrex glass (test tubes, stirring rods, beakers, tubing) disappear by submerging it into a variety of liquids, in this case cooking oil. This demonstration works best when the liquid is lit from the same direction as it is being viewed or lit from overhead lights, when the light source is behind the container of liquid it is easier to see the glassware "hidden" inside.
