Inventions, Dancing, and Inventive Dancing

Clara is a huge fan of being the center of attention, so she treats us to many, many performances. Tonight, it was a Camp Rock extravaganza loaded with leaping, twirling, posing, and strutting. Although Trevor was invited to perform, he was busy with a new invention.
He started out by taping a straw onto an inverted cup, and blowing through the straw. Then, he wanted to see if he could make cool air come through the straw. Hence, his invention, "The Cooler":
That blue thing is an ice pack, by the way, and he tried many positions before balancing it perfectly on top of that book. After he had finished, he came to the conclusion that not much air came through the straw if you weren't blowing. He said that next time he's going to find a way to just cool down his breath. I'm not saying we are responsible for his brilliance, but we did give him a name that rhymes with clever.

Clara eventually managed to convince Trevor to join her in a stirring rendition of YMCA.
Their costumes are bathing suits because, in Clara's words, "You go swimming at the YMCA. I don't know why they sing about having a good meal and all that. The Oakland Y just has a snack bar. That's not exactly what I'd call a good meal."
