Henry eyes the amulet and after considering this creates a thin crystal shield around it just in case the thing does explode. Then he absorbs the object, much more slowly than the other objects.

"I am trying to feel the sense of the magic, which is why I am going at this pace." He says after a minute. "Not really sensing anything different about the object." He reports.

After a while he has completely crystallized the object, and after another while he starts making a copy.

It turns outs to be non-magical.

Drat. Well, at least it didn't explode. Oh well. To make Tachyon feel better, here is how carbon becomes carbon fiber! Here are some other excellent materials that are hard to replicate! Here is what they can be used in! 

Here is a sandwich! Who's hungry? Fish gotta swim, speedy scientists gotta eat. 

They are ravenous. Using magic works quite an appetite 

Superspeed: handy for setting tables. Unfortunately it doesn't make things cook faster, so the resulting smorgasbord is mostly cold food. But there may be some things here that Henry and Gabe have not seen before. Summer sausage! Potato salad! Fruit salad! Regular salad! Pigs-in-a-blanket! Twelve different kinds of crackers and half again as many cheeses! Fruit punch! Chips and dip! Ice cream!

Oooh, they are delighted. Pigs-in-a-blanket is a hit. So is fruit punch. They seem to be familiar with the various kinds of food in general terms, but the local varieties are new. Henry and Gabe eat like a single organism, sharing food between each other and feeding each other.

"Aw, that's adorable. Is the food sharing, like, a cultural thing?"

OmnomnomnomnomNOMNOMMMMMM...

"Ah. Not really, the pairs of us just have an unhealthy lack boundaries."

"Does that predate your island adventure?" 

"Yeah, we grew up together."

"Is that unusual here?"

"Not really? The food thingy is the sort of thing that siblings or spouses might do. It's not super common in public, though, because people are prudes." 

"We can tone it down in public."

Gabe gives the most exaggerated pout.

"Or at least, I can."

"I reiterate: adorable." 

Eventually, all have imbibed enough sustenance. (Although the occasional cracker still mysteriously vanishes with a spark). 

Back to magical-science experiments?

Magic science! Impromptu metallurgy lesson! Brief detour to Spain to acquire some saffron! (Superspeed: the greatest)

Henry is delighted about metallurgy, he is curious what exactly they want from saffron.

It's another ridiculously rare and expensive thing that they can sell. Also, it's a moderately complex organic molecule. Two birds, one experiment! 

"Hey, you could make ethically-sourced proteins! Put the Magic Burger people out of business." 

"Yes, and three hours later Big Meat has spawned the first Anti-Eldritch Sustenance Only League, complaining of the evils of magically-altered foodstuffs." 

"I think they got the jump on us there, boss. I saw an article on Gibber the other day saying someone sued Doctor Potato because conjured seeds aren't FDA-approved." 

"What? But it's molecularly identical - ugh, never mind." 

"If I understood as much as I think I did, that sounds like a scarcity-driven dynamic that a society without our magic would generate. I shouldn't be surprised."
