Sensor/thermal bulb from a capillary tube. Likely from a refrigerator.

Alright, thank you! 17 years of wondering are finally over.

[–] ColeSloth@discuss.tchncs.de 17 points 1 month ago (1 children)

You should still keep your piece of trash just for the memories, now.

[–] BartrandDuGuesclin@lemmy.world 22 points 1 month ago

Of course! It is my most dearest piece of trash.

From a quick search, it is used to control the flow of refrigerant based on its temperature. The tube deforms based on how hot or cold the refrigerant is, and there are contacts on the tube to switches that permit or resrrict coolant flow

In other words, it's a simple thermostat

[–] Hamartiogonic@sopuli.xyz 5 points 1 month ago (1 children)

Wow, that’s pretty clever.

[–] ilost7489@lemmy.ca 7 points 1 month ago

Physics, yo

[–] Thorry84@feddit.nl 7 points 1 month ago

Just to add my 2 cents, it's more likely a filter/drier from a refrigerator. Those are much more common, even though a sensor/thermal bulb looks very similar.

[–] CM400@lemmy.world 48 points 1 month ago (1 children)

It looks similar to part of the cooling system on the back of my refrigerator.

[–] givesomefucks@lemmy.world 21 points 1 month ago (2 children)

Yeah. It's just random (relatively) modern piece of tubing that either fell off a boat or was tossed over board.

Cool memory for OP, and they picked up a piece of trash from the ocean.

[–] BartrandDuGuesclin@lemmy.world 12 points 1 month ago* (last edited 1 month ago) (1 children)

I always thought it might've came from a fishing boat. I guess that could still be the case. Pretty funny.

[–] givesomefucks@lemmy.world 12 points 1 month ago

Yeah, cool for you and a priceless reminder of a childhood vacation.

Just not something worth any money or even worth passing down thru the family.

If you ever watch Mitchell and Webb they have a bit where archeologists find a VHS cassette of a toga party and insist it's an authentic recording from ancient Rome.

Picking up trash under water is not the same as picking up trash on land. The small piece OP collected was probably ok, but the damage you can do to the ecosystem by removing a bottle or other big chunks that have been there for years can be really bad. I hope all divers have that in mind when they explore the underwater world.

Edit: I don't get the downvotes, I'm not making this up. It's one of the first things you learn as a CMAS diver.

[–] BartrandDuGuesclin@lemmy.world 4 points 1 month ago (1 children)

I can't confirm if that's true, but that is actually oddly interesting. Maybe the downvotes because... It sounds so weird?: adding trash to water is bad, but removing trash can also be bad?

It is really a headscratcher for me too, would like to read some info about it if you can share some sources?

[–] frisbeedude@feddit.org 5 points 1 month ago

There's just a different "quality" of trash. Something deeply embedded in the ecosystem will become part of it. If you plug a bottle or large piece of metal from the floor you will destroy some form of habitat. Floating plastic has to go of course, as well as strings or nets.

Another picture to have an idea about the size of it.

[–] VubDapple@lemmy.world 15 points 1 month ago (1 children)

It's conventional to use a banana for scale, but a hand will do in a pinch I guess.

[–] Ookami38@sh.itjust.works 20 points 1 month ago (1 children)

That hand is, in fact, in a pinch, so we have no problems!

[–] BartrandDuGuesclin@lemmy.world 7 points 1 month ago (1 children)

Ah, good. The problem resolved itself. I can continue being somewhat lazy

[–] kubica@fedia.io 5 points 1 month ago

And somewhat italian.

[–] BenLeMan@lemmy.world 6 points 1 month ago

Phew. The small size, combined with other people surmising it might be part of a refrigerator greatly alleviates my worries you might have picked up a piece of unexploded munitions from WW2. Which is an all too common thing over here in Germany.

Thank you, i will never stop calling it that now!

[–] lurch@sh.itjust.works 10 points 1 month ago

There could be dangerous coolant in it. When scrapping devices using coolant, the workers used to make it pump it into this chamber, then squish the end tight, roll it a bit, then remove it.

I think it is, yes.
