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.

Theyemerge from that data, the same way they do in the real world.Drop sodium in water and watch it fizz and ignite. Grind aluminium in themortar, dust it over rust, and strike a thermite burn hot enough to weld. Wiretwo different metals into a galvanic cell and light a bulb.

Flow is soft and luminous — smooth surfaces, depth-lit pools, every droplet part of one living body of liquid. Classic is the raw falling-sand look, every cell exactly where the simulation says it is. Same physics underneath, down to the pixel. Tap F6 to toggle, whenever the mood strikes.<h2 class="bb_tag" >A living encyclopedia</h2><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4933990/extras/4e748dcab2d9565c144a30d07d06d1ba.avif?t=1783630815" width=1472 height=1024 />Everything you make gets recorded in the Codex — a periodic table, a log ofevery reaction you've triggered, the dramatic phenomena you've witnessed, andthe tools you've earned. You start with a handful of elements; the rest of thetable unlocks as you hit real chemical milestones. It's a discovery enginedisguised as a sandbox.<h2 class="bb_tag" >Challenges</h2>Want direction? Take on challenges — goals that range from gentle to fiendish:evaporate a sea to recover its salt, forge a foundry of distinct alloys, reclaimmetal from its ore, neutralise an acid, grow a forest and then wipe it off themap with a nuclear blast.
