Keith leaned back in his chair, rubbed his eyes, and took a long sip of butterbeer.
Around him, the Three Broomsticks buzzed with activity - people left and entered through the inviting door, others ordered drinks, others stood and mingled, chatting amiably about quidditch, and the weather, and anything else that happened to cross their minds. All in all the place was packed - Keith had been lucky to get here early, when seats had still been open.
Keith took a deep breath and slowly exhaled, glancing back down at the complicated formulas he had jotted down on the papers that currently occupied his table. He hated the theoretical work, hated it with a passion. He was about combining things, and seeing where it went, and improvising. Except he couldn't exactly afford to do that just now so...theoretical work it was.
His problem was Spice. His problem had been Spice for a long time now, and he was fairly sure he was stuck. He took another look at the formulas and groaned, leafing through a large textbook in a vain attempt to find an answer to the question that had been bugging him for months now.
How do you get Spice to work in solid form?
The main issue with Spice, Keith had realized, was that it was liquid. It was difficult to transport, and to buy in bulk, and very very fragile, in the sense that you had to be extremely careful with it. But whenever he tried to "fix" it by changing it into a solid form, it seemed to lose all magical properties.
Keith was just happy nobody had tried looking over his shoulder yet. He'd hate to get kicked out again.
