The lab was chilly this afternoon. Allison rubbed her hands together and looked over at Ace, probably rather warm in her bomber jacket. She had forgone standard safety procedures; a lab coat was nowhere to be seen and the surfaces were covered in junk pulled from her impossibly large pockets. She was, however, wearing a slightly oversized pair of goggles, which had elicited an excited yell when she found them in a cupboard. "Just like a mad scientist!" Rachel would not have approved.
Now Ace held a small beaker in her hand, a clear bottle of an oily looking chemical in the other. As she measured, she snatched frequent glances at the scrappy paper beside her. The recipe for Nitro 9.
"You know," Ace said casually, "the last time I did this, my hand slipped when I was measuring and I started an accidental fire in the TARDIS lab. I don't think she liked that very much." She set the beaker down, grinning at Allison's mildly worried expression. "Don't worry, I know exactly what I'm doing."
She paused, checking her notes and gestured for Allison to pass her a slim container filled with powder.
"And after this batch of Nitro," Ace continued eagerly, "I'll show you how to make smoke bombs! They're wicked."
Allison couldn't help but smile at that.
