The above video could be used by a tutor to discuss some topics in high school and university physics but the best reason to watch it is just to be stunned by the spectacle of a very simple demonstration. I had never heard of Prince Rupert’s Drop until I chanced upon a mention of this video on a local medium-wave radio station.
The best educational use of this video might be as an example of how discoveries are made when new windows are opened. Our human senses are very limited. They show us so little of the natural world. Much of what has been learned by the scientific method has been the result of looking through new windows.
Astronomers build gigantic radio telescopes on the ground and fly telescopes above Earth’s atmosphere. This enables them to investigate cosmic mysteries at radio, infrared, ultraviolet, X-ray, and gamma ray wavelengths which would otherwise be completely beyond the range of human perception.
Microscopes reveal the microorganisms at the bottom of the global food chain and the bacteria that spread disease.
High-speed photography, as so brilliantly applied in the video, lets us expand time so that we can see the internal structure of extremely brief events.
