One night, I was casually scrolling through Facebook and came across a clip of a basketball player showing off an insanely high jump. It made me wonder how high I could jump.

I figured maybe 10–15 centimeters at most. But someone told me they could jump 40 centimeters. I said, “No way.” So I told them to prove it.

In the end, they barely got off the ground. It was pretty funny — and they weren’t even wearing shoes.

After that, when we told other people about it, everyone wanted to try jumping too. But in the end, no one could jump higher than 40 centimeters.
