Admit your ignorance - things you've only just realised/learned

Like this Twitter user I'd never come across quadruple-A batteries before

They're so tiny that - like neutrinos which are impossible to see, almost impossible to detect - most of us will go through life without even being aware of their existence.

And they last much less time than it takes to replace them, so AAAA-powered kit is off for 90% of the time even if want to use it 24/7!

It took me till the last 20 mins of the last episode of The Catch to recognise Brenda Fricker.

Jogging bottoms with elasticated cuffs on the ankles are called jobbie catchers 🤔

Freezer doors are held shut by suction - I'd always though it was magnetism
Recently ours stopped shutting properly, a quick clean of the seal and freezer soon sorted it

They usually are magnetic, but with an airtight seal that gets interrupted by debris or damage.

That's why when you first open a fridge door and then close it, it takes less effort if you then quickly reopen it. The warmer air that has replaced the colder air that was in the fridge hasn't had sufficient time to cool down and create a partial vacuum.

Yeah, the magnet is essentially there to hold the door closed whilst the pressure differential can build.

Does that mean if you put your fridge outside when it's (say) -4'c, the door might well gently swing open?

We have a fridge in the outbuilding which is now my Beer Fridge ( though Mrs Tenkaykev has started encroaching with items of veg 😮)
In winter it's switched off and the door held slightly open with a broom handle. Fortunately the alcohol content prevents the beer freezing when it gets below zero. 🍺👍

Not if the magnet is OK

That's a beer cupboard.

It’ll probably be off the hinges by the time you’ve manoeuvred it outside.

Does the magnet work when the fridge light is off?

Only with a cat inside.
