I’m surprised to hear that bluetooth, GPS, and cellular don’t work in water. I wonder what’s the science behind this.

water absorbs electromagnetic waves, especially high frequency ones. That's why your microwave heats things :D

Fairly big topic: https://en.wikipedia.org/wiki/Dielectric_heating

I've gotta give them props for the persistence. I would have just given up and bought a new iPhone. It's impressive that the iPhone survived the whole ordeal, without even turning off. And the amount of stuff they found makes me wonder why people don't use magnets on strings to search for lost things in European canals more often. Could be an interesting hobby.

There are TikTok accounts devoted to this (where else?) - it seems surprisingly common to find safes.

Earlier quoted context omitted.

"Ordinance" is legislation. "Ordnance" is the explosive stuff. Old ordinance can also be troublesome, but is rarely deadly.

I'm not GP but as a non-native speaker, thanks for the tip! I never realized :)

I'm a native english speaker, and I also never realized those were two different words.

How much volume of air must be inside a standard phone these days to make it buoyant?

There’s this anecdote of Steve Jobs saw a prototype for an iPod and dropped it in a water tank in order to proof his engineers that they could make it smaller, because it had bubbles of air coming out.

I just find the German text message entertaining. The words and syntax are great.

"Mir ist grad mein handy in den Landwahrkanal geplumpst"

Geplumpst! Sounds exactly the right word for what just happened.

"Jetzt könnte ich ein Bier gebrauchen"

Couldn't we all.

Maybe is the combination of rust iron, salmonella, chilling cold water and skin cuts. Aren't such big magnets an hazard for anything digital near them? Everything has a computer inside now, starting by cars.

Large permanent magnets are a fairly minor hazard to most electronics.
