Powder had already mulled over the question far too many times for it to be healthy.

She fiddled with her blueprints and notes as she waited at the table for you to arrive, looking over the messy scribbles and small doodles in the margins. In theory, the automatically zooming goggles she was trying to make should have been working fine. The lenses were adjusted properly, the gears were turning fine, but for some reason it got stuck after the second zoom.

One of her equations mustn't have been working, but which one was it?

Her thoughts were interrupted a second later by you plopping down opposite of her and gesturing to the blueprints, half a biscuit in your mouth.

"Here, take them," Powder grumbled, tossing you the papers and grabbing the other half of your biscuit out of your hand, "It's driving me insane. I can't see where it's wrong."
