A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Metal is plastic. (lemmy.sdf.org)

In materials science, "plastic" refers to the ability of a material to undergo permanent deformation under stress without breaking. Metals exhibit plasticity when they are subjected to stress beyond their elastic limit, allowing them to be shaped or formed. This property is distinct from the common use of the word "plastic" to describe synthetic polymers.

Perhaps you meant to say that ices are crystals?

No. In astronomy, everything heavier than hydrogen or helium is referred to as metals. So, a star's metallicity would be including carbon, oxygen etc.

In my country we refer to gravel roads as metalled roads, for no reason I can explain.

"It's called blue metal since it has a blue colour."

That explains the blue, but not the metal...
