So the dramatics in class were already getting underway, which was not only expected and typical, but it was just how Ariadne liked it! She literally never got bored in this class. EVER. She just listened to the first part of the discussion, because everything she could think of had already been said. She just nodded along to show understanding.

...and then there was a second question. She could probably answer this one.

STAR. She'd talked about a STAR.

No, no, no! A COMET! She was settling for comet, and to seal that deal, she raised her hand. "Hmm...a comet, professor! Let's see...picture a snowball. Only, picture it being all dirty and nasty and icky instead of pretty and white. This is basically what a comet is," she explained. "It's got ice in the center, which sounds kind of cool, but then it's also mixed with carbon dioxide and a few other things--like dust! The Sun ends up warming the ice, and it pretty much goes POOF! Then as the comet gets closer and closer to the Sun, the gas starts to get hotter and hotter and hotter until one day, it just separates and forms this tail! So what you end up with is a dirty snowball with vaporized ice and a tail of wandering gas. Pretty cool, huh?"

BREATHHEEEE. *GASP*
