    Introducing the pneumatic oven range. Place the chicken in the can and press the button… No mess cooking and bone meal blending! High calcium foods!

    Yeah yeah we get it, Newton will fry your hand and pls don’t cook a chicken to 205°C core temp.

    BUT! What kinda physics major forgets Newton AND the fact that you won’t convert kinetic energy into heat with 100% efficiency?

    I know, three math majors in a trench coat, that’s who’ll forget it.

    Gotta love how everyone forgot about Newton in all this. Enjoy your instantly well-cooked hand, which is also made of meat.

    As your friendly neighborhood person with knowledge about food and cooking, 2 pounds is an absurd weight for an uncooked rotisserie chicken, that is a very small and cooked weight, 4-6 pounds is going to be typical. Also, more importantly, you cannot cook something faster by increasing the temperature past a pretty quick point, meat is an excellent insulator. No slap can cook the inside of a frozen chicken unless the entire chicken disintegrates.

    Tbf though, a slap at 3700 mph would absolutely disintegrate the chicken.

    Lord have mercy on folks cooking their chicken to 400 F. Those birds will come out as dry as the sands of the Sahara.

    Typical physicist, ignoring enthalpy of phase changes. Starting from 1C defrosted makes a huge difference from 0C as the melting takes up a ton more energy/slaps. Their underslapped chicken would give you salmonella

      They haven’t considered rate of slap. Significant heat transfer to environment even at 10 slaps per second.

      They’re also assuming sea level standard atmospheric conditions. You may need to reduce rate of slap at altitude.

        Also only about half the heat goes into the chicken and the other half into the hand used for slapping

          This assumes both have the same amount of heat capacity * mass. A hand with heat insulating gloves would also significantly reduce heat loss.

          Better do it in a vacuum though, you’ll lose energy to air resistance

      Also completely neglecting that not all the energy in a slap will be transferred to thermal energy in the chicken.

        I confirm this as a physics PhD. I also understand exactly this thinking of assuming a system is in thermal equilibrium where it is far from it (like a chicken in am oven).

        You need the chicken to be 165F or 74C to be food safe. It takes a long time to cook at 100-200C because the heat is being transferred much slower. If we’re using this instant slap-based cooking method, it only needs to get to the food safe temperature.

        Using the OP’s calculations and a cooked temperature of 74C:

        It would take 8315 average slaps

        or

        A slap at around 813m/s or 1819mph.

        *Edit for a correction to the second calculation (it still might be wrong), also, I rounded the numbers to whole integers.

    What if I wanted to cook the chicke through friction, by say inserting an object 3 fingers or so thick in and out of its cavity as fast as athletically possible? … so um… how long can I keep fucking my chicken?

      Naw, that’s burnt.

      Maillard reaction where things brown starts at 350f.

      More than 165/175 in the center and that’s dried out.

        I saw your username first.

          I thought about making an intentional joke about being the “mallard reaction” and saying “isn’t that quackers” or something, and decided to not confuse people.

          naturally. Best to slow it down and keep it juicy, too. I like smoking them at about 200 f, it’s perfection.

          also… way to make spatchcocking sound even dirtier than it is. the no cooks here are probably thinking it’s some sort of sex act and the rest of us are wondering if it’s not also some sort of sex act.
