Cam wishes to convince his vitamin to be better at being a vitamin. Ideally, it could supply perfect micronutrients for whoever took it with some sort of time-release so it wouldn't be necessary to have a new one every day for the vitamins that humans can't store effectively, but he'd settle for omitting side effects like niacin flush or some other measurable improvement in the performance. What does his manual have to say about that?
"If you take niacin, even the right amount of niacin, if it's more than you were getting before you get some side effects," says Cam, showing Jellybean the warning on the bottle.
Cam starts asking his manual for general information about getting things to work in different ways in general.
"...Okay." Cam goes back to narrowing down what he's looking for from the manual without getting too narrow, with Grace's help.
They don't make a lot of progress, and after a while Cam switches to a potato of his own. He already has a fair number of spells pulled on the subject of food and knows how to make the potato taste like chicken. Can he make it have other features of cleverer products? Can it taste like beef, can he fuss with the macronutrient content, will it consent to pass on characteristics like that to its sprouts?
Cam solicits information on outright genetic manipulation, in case someone's come up with a way to get around this reluctance. He's also listening with half an ear to what in the world Jellybean's doing with his potato.
Cam blinks, and pays attention. He doesn't interrupt Jellybean; he does not yet know how to do that productively instead of distracting the other wizard into making the potato sing songs or write the Great American Novel or something instead.
Cam peers at Jellybean's potato, and at his own potato, and he attempts to mimic the style, just in case it'll work.
He decides to wait to see if Jellybean gets around to more useful changes than darkened color of his own accord before attempting to prod him into it. He carries on with his own approach to the project, and takes a bit of a listen to what Matilda's doing between attempts.
Jellybean convinces the potato to have a nutrient balance closer to the ideal ratio for human consumption. He doesn't say it like that, though, so it might take some listening to figure out that's what he's up to.
Grace is helping, so Cam figures it out eventually. He doesn't interrupt. He does, however, give up on his potato - since Jellybean is making more progress and there's so much more to do - and get a grain of rice.
Okay, that's interesting, if they just vary in cooperativeness. Cam tries other available plant-based foods, finds rice the most suggestible, and sets about convincing the rice to do useful things, taking notes as he goes on what he's trying and what works.
"Yeah. Arizona's not really great for it, but I guess if we can make them take root in the backyard here, that's a good test of how they'll do in, like, the Sahara, compared to if we went someplace cooler?" says Cam. "So there's here, it's not like the sand in the yard is doing anything that Renée'll be annoyed if we mess up."
