"Yeah - that's clearly the way to go here, right? Like, objectively, alertness or whatever else you're going to learn to do is a good deal, if you were selling potions at the same price all the kids who can afford it would get it, and a bunch of them are missing out because they don't want to seem weird! Which is normal! We're fourteen! We're in the middle of the identity formation process and we're very sensitive to the approval of our peers!" Julia read that in a book and doesn't understand it well enough to attempt rephrasing it. "But if everyone's doing it, then the case for it is overwhelming, and eventually it's - a status signal, right, eyeshadow communicates that you can afford to invest in your own safety and alertness and attentiveness - honestly my advice once you've met existing demand might be to give out samples super cheap, so people experience it and know they want it and know it's worth it and see everyone else wearing it. Maybe even give it out to upperclassmen basically for free, or for the price of supervising in the lab while you make it, because if all the upperclassmen have it then the freshmen will think of it as aspirational, right?"
