…This is a weirdly difficult prompt, actually. That’s not Merrin’s thing! She’s not into Cool Science Tricks, really, her thing is whatever works to keep people alive in weird emergencies. Some of her trainings involved less and lower-tech gear than what she had for this one, but she can’t think of anything that came up in her actual Exception Handling work that could be done with only basic local materials and would look impressive. Like, sure, she can light a fire without any fire lighting tech - that wasn’t even Exception Handling stuff, that was Kalorm showing off - and, like, alternate-Estha's planet clearly has basic nonmagical tech, they use metal, they have textiles, they can presumably nonmagically light fires.
If she were more of a protagonist she would know how to make strong acid or something from, what, rocks? even if she arrived on a planet with nothing but her clothes? - as it is, she's pretty sure she can make hydrochloric acid by seawater electrolysis but that takes, you know, electricity, and titanium for an inert electrode - really it's impressive that she remembered that off the top of her head, she's never that she can recall done that, she's a medtech–
Nope. Over it.
Merrin needs to stop thinking of it in terms of cool stuff that she can do, and start trying to think of - what - science experiments done by eight-year-olds? Any anecdotes she can remember from anyone she knows who is the sort of person who does Cool Trick Science for fun?
Hmmmm.
.....Which of the following Baseline concepts have translations in any of her Shared languages: optics, magnetism, static electricity, air pressure, cells (in the biology sense), ummmm, acid-base reactions? batteries? thermometers? pendulum clocks?
