Fun fact: someone actually did it
incredible engineering feat !
this will definitely fulfill someone’s kink.
I was going to link it if no one else had. Glad I wasn’t the only one that recalled that lol
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.
😭 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)
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.”
morpheus, that you?
Oh, in that case it only needs 9,213 slaps (delivered near-simultaneously) or a single slap at 1,490 mph.
Also why is it starting off frozen
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=1458s
What I learned from this is never let a physics major cook you dinner, unless you want charcoal for chicken (200C !?!)
Yeah 60c is done for chicken. That’s where meat goes from pink to white. It takes 18 min to kill dangerous food bacteria at that temp.
I was gonna say to start laying off when it gets to 165F, I don’t think residual heat will help in this case 😁
And they didn’t defrost it first 🫠
0 C wouldn’t quite be frozen solid for chicken since it’s not pure water. According to a quick search, chicken (unbrined) freezes at -3 C. So technically it is defrosted, but it should start out closer to 10 C for good results.
But it only needs to reach 165°F, about 74°C.
Basically every food package says so.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.
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:
Came here to post that video It’s such a great watch
I was hungry
not anymore
I’m hungrier because I put so many calories into slapping.
Why isn’t it a concern what slapping at this speed does to your hand/arm?
If you could have a superpower, what would it be?
Me: I’d like to be able to slap fast. Like really fast.
The chicken ran away when I tried to slap it.
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.
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
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.
So the flash could cook a chicken by slapping it
