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!
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.
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
There was a viral YouTube video of doing exactly this a few years back.
Damn, this thing slaps
If you could have a superpower, what would it be?
Me: I’d like to be able to slap fast. Like really fast.
I once watched a youtube video where someone built a rig to explore this very question
Didn’t someone build a machine to do this
Wait a minute 400°F? What dafuck?
He confused internal temp with oven temp lol (I still probably wouldn’t cook a chicken at 400° though.)
I cook it at 450, 10 min each side. Works pretty well & you can get some browning with no oil.
Let’s assume the chicken has to reach a temperature of 205C (400F) for us to consider it cooked.
Remind me never to let this guy cook for me.
Julia Child did some 400° cooking, for a science-oriented TV series called “The Ring of Truth”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=850s
Later in the episode, she got to cook a diamond to amorphous carbon. “I’ll remember that recipe – one carat diamond, two and a half hours, three thousand degrees”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=1458sHis roasts be literally disgusting. He’s off by 2x. Does that mean I only have to slap the chicken at about 2k mph to cook it like a normal person.
Also why is it starting off frozen
You can’t cook chicken with math, it’s out of this guys wheelhouse
😭 chicken dry as a bone. I think they were conflating the oven temp with the desired internal temp (165 F is the safe minumum for poultry for the curious, so 400 F would be well done to say the least)
Tbf, he doesn’t account for the loss of heat at all, so it’s good that he’s taking a big margin.
I think the phase change costs of the water content will also be a significant factor that isn’t included.
Good point
Oh, in that case it only needs 9,213 slaps (delivered near-simultaneously) or a single slap at 1,490 mph.
“Consecutive normal punches”
Dry as a bone would be an understatement, it would be charcoal in a puddle of fat at that temp
“It’s a single-celled protein combined with synthetic aminos, vitamins, and minerals. Everything the body needs.”
To be clear, the slapping would have to be done in one single second to account for heat loss to environment.
What if you wrap it in a blanket?
It’s expected there will be some heat loss over time in any scenario, I’m just explaining that the exact numbers to reach 200C chicken (way overcooked) in this very specific example only work if it happens near instantly.
You can still cook it over time, easily, just with different numbers than this example.
I didn’t check the calculation, but I guess it assumes perfect conversion of motion to heat. But it’s good to know that if you can get a perfectly static chicken, you can hypersonic-slap it cooked.
I read once that the Mongolian warriors would place raw meat under their saddles and after riding all day would then consume it. Now I’m thinking that’s not so far fetched.
This isn’t going to be accurate, it’s ignoring a key aspect of the heat that will be generated, friction. When designing materials for prosthetics we have to be aware of how much friction occurs between the material and skin. If the amount of friction is too great, the material can create enough heat to damage tissue.
The formula for the skin friction coefficient is cf=τw12ρeue2, where ρe and ue are the density and longitudinal velocity at the boundary layer’s edge.
It’s also ignoring your hand would also heat up, ignoring the energy converted to sound, ignoring the heat loss to the environment, ignoring both your hand and the chicken would disintegrate if you hit it that hard, therefore transferring most kinetic energy without converting it, ignoring the enthalpy of fusion (they said it’s frozen)…
TLDR: it’s silly, just for funsies
