⚗️ Particle LabPlay
Particle Lab is a physics sandbox for open-ended experiments. The menu on the right holds nearly two hundred substances: powders, liquids, gases, metals, explosives, electronics and even living cells. Every particle tracks temperature, pressure and charge, so ice melts next to fire, metal carries a spark and pressurised gas bursts through walls.
Build circuits from wires and sensors, set off explosions, grow plants or put machines together. Display modes reveal heat, pressure and air velocity. Your work is saved in the browser, and every new substance you try raises your score on your Levbee profile. The game is based on the open-source The Powder Toy.
