Have you ever wondered whether it’s possible to cook something just by hitting it?
No, neither have we.
However, in 2019, a Reddit thread posed the question: "If kinetic energy is converted into thermal energy, how hard do I have to slap a chicken to cook it?"
And one man was inspired.
Two years later, YouTuber Louis Weisz decided to find out once and for all if heat generated from slapping a whole raw chicken thousands of times could render it edible.

In a video titled I Cooked a Chicken by Slapping It, Weisz revealed that it took him two months to successfully carry out his culinary experiment.
Having created a special slapping device – featuring a wooden paddle attached to a motor-powered arm – he was forced back to square one when the contraption collapsed.
Back to the drawing board, he realised his design needed three core elements: “a faster slap rate; more impact control, and minimal heat loss from the chicken.”
He then made a stronger “oak core aluminium” arm which could hit the chicken at speed without reducing it to a messy pulp.

Eventually, it took a staggering 135,000 slaps over the course of eight hours to slap-roast the meat.
This amounted to a whopping 7,500 Watt Hours of energy – around two to three times the amount needed for your oven to carry out a similar job.
Weisz also cooked a steak using the same slapping method and, while he admitted the texture was “kind of bad” and tasted like “you’ve been chewing it for a minute already”, he added: “If you can get past that, it actually tastes pretty good.”

He didn’t, however, tuck into the chicken. Because, although it was cooked through by the slapper, a tear in the bag in which it was contained meant the meat was contaminated by fibreglass and aerogel during the process.
So, in sum, you can cook chicken – and steak – with slaps alone but… do you really want to?
