“Did this shark brush its teeth properly?” asks CandiCrush, “there’s an odd smell of fish!”
“Chemicals probably!” replies BarmyWaffle, “we have lots of them. Come and have a look.”
Everybody moves further down, towards the cabinets at one end of the lab.
BarmyWaffle has some questions, “HayWire, Max, you were making hydrogen weren’t you? What did you use?”
MaxChaos knows that a goat’s bladder was involved, but leaves it to HayWire to explain the rest.
“Iron shavings added to hydrochloric acid. Drain cleaner actually! I don’t have access to anything serious where I work.”
“We do. We have hydrochloric acid, and sulphuric acid too. Though we use them mainly for cleaning things, removing impurities, that sort of thing. We don’t use any of it as a component in a process. Fluid dynamics is a challenging subject. I know it, but Tom and Jerry don’t. Anyway, we don’t need complexity.”
HayWire joins in, “fluid dynamics is fine, I don’t know why everybody gets so het up about it, even my GuildMaster! I know it’s difficult for some people, but I don’t understand why!”
BarmyWaffle is surprised, “where did you learn fluid dynamics? They don’t teach it in schools. They did that at universities in the old days.”
CandiCrush interrupts, “Barmy, turn on the fan in the fume cupboard, all these smells are getting to me.”
Excited, HayWire wants to launch into a detailed discussion, “Mr Whitton, my maths teacher! He spent extra time with me outside regular lessons, taught me calculus, and then I started reading more. I asked him about Navier-Stokes equations. He only half knew it, so we studied it together. Best teacher I ever had!”
“You understand non-linear partial differential equations?”
“Theoretically, yes, never used them in practice!”
