This video, titled "For Future Scientists｜#14 A Return to Superhydrophobia!" ( 未来の科学者たちへ #14「超撥水ふたたび」), was released by "nimspr."

This is the 14th episode of the popular "For Future Scientists" series, "A Return to Superhydrophobia," in which you can learn about basic science using everyday objects.
As you can see from the title "A return," the previous episode was about the theory and experiments of super hydrophobia, but this time, two easy to understand experiments are conducted to show how super hydrophobia works in real life.
Both experiments can be done with easily obtainable materials.

For super water-repellent coatings, water-repellent sprays and paints sold at home improvement stores could be used as substitutes.
If you're interested in trying these experiments out, be sure to give them a try, as it's easier to learn through hands on experiences!
