    Using cooked meat or not, almost certainly not going to get hot enough to pasteurize and not airtight to prevent contamination.

    So…sounds like a perfect incubator for bacteria.

      I don’t know where this is but it doesn’t sound impossible to me. A quick Google shows that the FDA recommends 160 F for casseroles and that in direct sunlight a car can hit 160 if the ambient temp is >105 F. I know mailboxes aren’t cars, but over a longer period in a smaller metal box, it seems like the math could check out

        I live in Utah where it’s been sinfully hot and dry for the last week. I fully intend to test this theory. I just bought a high temp probe that should get here tomorrow. I will provide an update once the testing has been completed.

          Alright, I have the sensor installed. It’s a bit cooler and more overcast today, but I’ll hopefully be able to get some good data.

            I don’t know if this could inadvertently dox you but I’d be curious to see an hourly outside temperature too to see how much hotter a mailbox gets than outside. Based off your first graph here I’m wondering if cars having glass windows makes a greenhouse effect that would make a car hotter than a mailbox, everything else equal?

              Seems like a worthwhile thing to do! I’m not worried about doxxing, since someone would have to go to pretty extreme measures to correlate with the exact climate where I’m at. I installed the sensor after the hottest time of day had already passed, but here’s what it looked like:

              A graph showing the outside temperature versus the temperature in the mailbox.

              I’m pretty sure the spikes in the mailbox temperature were due to cloud cover.

            By the way, just a quick tip, if you haven’t already maybe try airgapping the sensor from the metal with some foam so you’re measuring the air itself.

              I have it positioned right now so that the probe tip isn’t touching any metal, but I’ll probably add a bit of foam. I have some incredibly irritating foam packing peanuts that would probably work well. I’ll go do that now.

              EDIT: here it is, in all its gloriously crappy, uh, glory:

              a picture of a temperature probe poking into the inside of a mailbox. A Styrofoam packing peanut with a hole in it has been put over the probe to stop it from touching the walls of the mailbox.
