You can experience this if you hit a coin with a hammer a few times.
So the flash could cook a chicken by slapping it
One thing to note, actually cooking something requires an application of heat over time. Instantaneous heat transfer will not cook, it will usually just burn.
Some people say you can use a nuke to cook a pizza if you put it in the right spot, but the same problem would apply.
Related, some guy did actually slap a chicken into being cooked. It was predictably disgusting:
It is about 1:06 when I first heard him call it a meat beater.
He needed a faster meat better. Bruva, we are right here!
Came here to post that video It’s such a great watch
There are so many weird assumptions here. There is more than a hand moving when a slap is performed.
A skilled slapper could put more of their body weight behind the slap. I’d assume at least 40 kg or even more as the average slap.
Average rotisserie chicken is 2 lb? Costco’s is 3lb. That would require many more slaps.
Fun fact, 165F is often parroted for cooking chicken, but I urge everyone to go lower. 155-160F results in much juicier chicken. 165F corresponds to instantaneously killing all bacteria. 155F is about 60s, and 160F is 15s.
And for even juicier chicken, directly inject cranberry juice using a needle and syringe. You can use other juices, but IMO, cranberry goes best with chicken.
For outrageously juicy chicken, sous vide to 155-160F directly in cranberry juice (no vacuum bag). This may bring the chicken beyond many people’s juicy limits, so I suggest trying the other two recipes first to gauge your personally acceptable limit of juiciness.
That’s assuming an isentropic chicken though. You need even more slaps to make up for the heat loss to the environment.
Don’t forget, the chicken is frozen, so you also have to take into account the latent heating fusion to melt the chicken before you can raise the temperature
This calculation also assumes that this is an inelastic collision where all the energy is absorbed into the chicken and not into your hand or into the air as sound or other kinetic energy.
Further the chicken is frozen solid, and, presumably, your hand is not. Of the two objects in this collision that could deform inelasticity and absorb the larger fraction of the energy, my money would be on the 0.4 kg slab of raw meat rather than the 1kg frozen billiard ball.
One must also consider the thermal conduction of the chicken. Slapping it, either once or multiple times, on a single area will impart energy to that area, raising the temperature there, but it will take time for that to disperse throughout the fowl. Thus will inevitably lead to the slapped area/areas being overcooked and the rest being dangerously undercooked. Losses to the environment must additionally be taken into account unless sufficient insulation is employed to mitigate this.
So would you say that a rotisserie slapping technique would optimal in this scenario?
It’s optimal for your mom!
Yes, I think the chicken would need to be rotating, you should use both hands to spread the warmed area, and be prepared to administer more slaps than were calculated.
Isn’t 1600 m/s greater than the speed of sound? That sonic boom is gonna mess up the kitchen, if not the hand.
Since we’re being pedantic, the feeezing point of unbrined chicken is -3 C. Most meats are not frozen at exactly 0 C since the water contained in the cells is far from pure.
But yeah, slapping will be a super lossy process and this analysis will be off by quite a bit.
Touché!
I wonder if there’d be any fractional freezing at 0C 🤔
Great… now I’m imagining raw chichen slushie 🤮
Why isn’t it a concern what slapping at this speed does to your hand/arm?
Because we are men, and men feel no pain when we slap things.
This is why we slap each other on the back after losses in sports, and why pimpin ain’t easy.
At 400F it would no longer be a chicken but a pile of glowing cinders. A chicken is cooked at 165F.
The real question is if you slapped hard enough to raise the temperature to 74C (undergrad clearly doesn’t cook), what would the temperature of your hand be? And for the engineers: how far up your arm would you have to measure before the temperature returned to normal body temperature? And for the bio/kin/nursing/premed students: how much would need to be amputated?

Hi there! I’m a certified surgeon in my DnD roleplay and I can safely say you’ve just amputated your own arm at that speed at just below the shoulder!
Lol i dont know the math but the speed required to apply that force means theres a sonic boom as well right? Along with the bubblewrap crack of your arm shattering in the process of somehow applying this force/acceleration. I actually wonder if there would be heat before the slap since the distance traveled is so short. Is there enough air between your windup and the chicken?
That’s like… 4 or 5 times the speed of sound at sea level so… There would be a bit of a boom.
My hand is a lot smaller than a chicken, so I hope everyone is prepared to have roast my hand as well
When Martha from accounting last asked me what my plans were for that night, I told her I was going to slap my chicken.
She won’t look me in the eye any more.
Yeah, I also don’t talk with people who engage in animal cruelty
I was hungry
not anymore
I’m hungrier because I put so many calories into slapping.
How many though? Could please someone think of the math? 😭
About 132 kcal, if your calorie to chicken heat transfer is 100% efficient.
For the 23k average slaps or the one with hypersonic speed?
They work out to the same total amount of energy.
Including acceleration and deceleration? Hm
The kinetic energy of an object is equal to the energy that was required to accelerate it.
205°C? You’re slapping your chicken too long, son. Your mother and I are worried.
The chicken ran away when I tried to slap it.
Geez, you need to freeze it first. Didn’t you read the abstract?
