The law of conservation of energy states that energy cannot be destroyed. It is simply converted to another form. So the next logical question is: can we cook a chicken by slapping it repeatedly?
The answer is yes! Apparently, this was a meme on many internet forums, but I only discovered it now.
This guy “cooks” a chicken by converting kinetic energy into heat. Spoiler: it “only” takes 135,000 slaps!
