Refractive Index - Part 4 - The Disappearing Penny Trick

The video demonstrates an experiment to highlight the refractive index using a penny, a glass, and water. It explains how light bending makes the penny appear to disappear and reappear, referencing a previous video for further explanation. The experiment is safe and requires no protective gear. Observations show the penny's apparent movement due to light refraction.
