Europea brooch entry part 2 INSIDE

's contesty thingy

my entry part 2

LOOK MA, IT MOVES! Like water, get it? Cause wikipedia says that the inside of Europa, just under the ice crust is a liquid ocean, then two parts that're solid-er-ish. So on the inside of the brooch, we have a solid outter ring, and then a section of liquid, then more solid-y-stuff.
