EIGHT SMALL EXPERIMENTS

Leave no pearl behind.

BEHIND THE GLASS

Very small doors.
A very big idea.

Recent membrane research explores how tiny channels can pass lithium while holding back other ions—one route toward recovering battery minerals from brines.

Brineglass turns that idea into a fictional puzzle. Here, every ion moves with your pulse, and each membrane simply follows its printed rule. The puzzle rules are invented, rather than a chemistry simulation.
