With laboratory technology against myths and click-bait videos: the egg in the fridge door

No, it has nothing to do with computer technology, not even removed with egg-T. But I was just fed up with looking at the same nonsense all the time and time. to have to read it. At some point, even the most patient consumer of the German quality media has reached a certain limit, where one simply wants to empty one's stomach contents. At that point I had just arrived at a video on Focus Online and yes, I just had to make a video about it myself.

The steep thesis that eggs do not belong in the refrigerator door because they would then be exposed to very strong thermal shocks when they were opened, which in turn should lead to the destruction of the popular food egg, was then too much. I have invested some measuring varnish and Sunday time to get to the bottom of this myth with my Optris PI640 times. You know, the infrared camera, which usually always finds the too hot memory modules.

This time, however, it was about the exact opposite, i.e. the Cold Spot. But what, please, is a "temperature shock" a la Focus Online? Analogous to mass inertia, one often talks enough about "thermal inertia" and it will be interesting to find out how long it takes to register really "omenacrising" temperature changes. The shell is made of lime, a very bad heat conductor and without any sense, evolution certainly did not strike here either. Because even a hen has to move up the butt from time to time when brooding.

I know such things as temperature shocks only from development to test the stability of certain assemblies or printed circuit boards. That's called environmental and shock testing, but what's the point of my fridge door? In today's video I measure for 5 minutes what really happens to the temperature. Refrigerator internal temperature in the egg compartment is approx. 8 °C, the ambient temperature in the laboratory is approx. 22 °C. The rest are expensive measuring varnish, a calibrated infrared camera and of course hEIner, a brown, open-air chicken egg.



Myth busted, but something like that. And I would recommend to the editors of certain media to simply press the school bench again. Thermal Theory, Class 8. Even the secondary school is enough for this, if you are careful. And anyone who remembers how long it takes to solidify an egg with a 90° hot baking plate knows that with the shock, it's just click-bait. Sure, it has nothing to do with our main subject area, but it is applied technology for everyday life.

After the holding of time, a white, slightly grooved layer is formed on the ground.


And as far as the rest is concerned, what the initial medium can do, we can do for a long time. Right and justified for that. So don't leave the fridge door open for 30 minutes and please – don't forget my tip with the milk. It certainly makes sense. I wish you a successful start to the new week! So long… 🙂
