But it only needs to reach 165°F, about 74°C.
Basically every food package says so.

This is correct; always cook to temp.

What I learned from this is never let a physics major cook you dinner, unless you want charcoal for chicken (200C !?!)

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.

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.

Luckily, it’s a linear relationship and they gave us the temp change per slap. So, if we assume the chicken has thawed in the fridge (40°F) and we want to reach 165°F for food safety, we only need

(165 - 40)°F * (5°C / 9°F) / (0.0089 °C / slap)
= 7803 slaps

Although, to be honest I think this would only work for a spherical chicken in a vacuum, as otherwise you’d be losing too much heat between slaps. And even in a vacuum, you’d lose some heat via radiation… So really, you should stick a temperature probe in there and just keep slapping until it reaches 165°F. Don’t even bother counting.

Sorry for the silly units, I only know food safety temperatures off the top of my head in °F.

I was gonna say to start laying off when it gets to 165F, I don’t think residual heat will help in this case 😁

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

Oh, in that case it only needs 9,213 slaps (delivered near-simultaneously) or a single slap at 1,490 mph.

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.

His 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.

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

Damn that was impressive! Also, I’ll have to let my little brother know that if he keeps beating his meat so much he might accidentally cook it.
