About
A falling-sand sandbox built on the **real periodic table**. Every element has genuine physical properties, and reactions emerge from real chemistry — rust iron, ignite thermite, run a galvanic cell, split a uranium pile to criticality. Discover it all in an encyclopedia that fills as you play.
