I came across this on one of the industry newsletters to which I subscribe.
The video below demonstrates what is called the Dzhanibekov Effect, first demonstrated by Soviet Cosmonaut Vladimir Dzhanibekov in 1985. It is also known as the Tennis Racket Theorem and the Intermediate Axis Theorem.
It’s neat effect that can be described by a lengthy physics equation, but this video provides an much more interesting explanation and practical demonstration of the Dzhanibekov Effect
I thought it was kind of cool. Then again, I am a tech nerd and I find this kind of stuff fun.
