Scientists, pockets, engines, and bottles have this in common with me.

I start out small and quiet, snug in my shell, then I dance and I leap when the heat makes me swell. I’m buttery or sweet, in a bowl or a sack, movie nights aren’t complete if I’m not coming back.

Amongst the fields of wheat and hay you often see, odds are there's big ol' me! Make sure to keep me under lock and key, otherwise you'll drown in more than just fees!

The more I dry the wetter I get, what am I?

I am Something that is nothing to what I once was. you may find me in the desert wrapped in tan cloth. I start to roam if you happen to be out at night, yet when the sun rises steady I walk still.
