Energy can take different forms and be converted from one form to another via certain mechanisms, as the famous adage of Antoine Lavoisier reminds us. It is therefore quite natural that the Youtuber Louis Weisz (engineer specializing in the implementation of experimental protocols intended to test various phenomena) wondered if the conversion of kinetic energy into thermal energy made it possible to cook a chicken. In other words, can hitting a chicken fast enough and long enough replace a pan or oven?
Have you ever wondered if you can cook a chicken just from the heat generated by slapping it? That’s the question YouTuber Louis Weisz asked, and the verdict is: yes, it is possible. As can be seen in the video, the effort took a lot of work – two months in total – from setting up the testing protocol to building a super-fast (and customizable) chicken slap to make cook the animal.
At the end of the experiment, Weisz gets a cooked chicken. The two key parameters were to retain slapping speed and striking force to heat the meat without disintegrating it and to limit heat loss – and as the video shows, both conditions were met. The physics supporting the phenomenon is relatively simple.
It’s possible that a 2019 Reddit post was the inspiration for the video, as it originally posed the question of whether kinetic energy converted (movement) into thermal energy (heat) could cook a chicken.
Slap fast enough and long enough: the key to cooking
Among those who answered this initial question, there was a physics student who suggested that one slap would suffice; if this slap had a speed of 1666 meters per second or 6000 km / h. Possible then, but not exactly viable – and other solutions have come to the same conclusion. It was only with a lot of mechanical help and a specially configured holding structure that Louis Weisz was able to cook his chicken.
Using a tip from Modernist KitchenWeisz figured out that keeping the chicken at around 55-60 degrees Celsius, for at least an hour, would be enough to cook it; or at least kill the same amount of bacteria as with cooking at a higher temperature over a shorter period.
After several unsuccessful attempts – mainly on the mechanical side – Weisz finally succeeded. In the final calculations, it takes a minimum of 135,000 slaps over no less than 8 hours to cook a chicken, using around 7,500 watt-hours of energy (two or three times more than your oven would need for the same job) . Weisz was even able to cook a steak using the same method.
