Found this when snorkling in Greece about 17 years ago when i was just a kid. Always wondered what it was... Anyone an idea? Almost certainly made of metal and i think it is hollow on the inside. (lemmy.world)

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

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

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

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