A puzzle piece of a bloom, A tiny burst of sweet perfume. Floats on water, soft and light, After a fall and short flight

I go up when it's hot and down when it's cold, but I never move myself. What am I?

I sit on the brows of villains and kings, From Doc Brown's lab to the Steampunk rings. The Minions adore me, and Cyclops must wear My frame on his face just to harness his stare. I shield you in winter, I seal in the sea, But no everyday glasses can claim to be me. What am I?

When I dry, I get wetter. lol Don’t even try to answer sponge, mop, rag, or napkin. You’ll never guess what am I!

I rise, then brown beneath the heat, and often make a meal complete.
