Elemental Sandbox — Interactive Chemistry Playground
Explore all 118 periodic table elements, synthesize real chemical compounds, and discover novel reactions in a free browser-based chemistry sandbox.
Periodic Table
Browse and interact with all 118 chemical elements — from Hydrogen (H) to Oganesson (Og). Filter by element category (alkali metals, halogens, noble gases, transition metals, lanthanides, actinides, and more), search by name or symbol, and add elements to the Reaction Vat to observe real chemical reactions.
Synthesis Lab
Choose from 47 built-in compound recipes and combine elements to synthesize real chemical compounds such as water (H₂O), salt (NaCl), ammonia (NH₃), sulfuric acid (H₂SO₄), and many more. The procedural synthesis engine also generates novel compounds with realistic physical properties.
Stress Lab
Apply thermal and mechanical stress to compounds and observe how they respond. Test melting points, boiling points, and structural stability. Compound-specific visual effects illustrate each stress response in real time.
Formula Lab
Enter any chemical formula and search it across PubChem, ChEMBL, and Wikimedia chemistry databases. Look up molecular weights, IUPAC names, and compound data for thousands of real substances. Import results directly into the Reaction Vat or Stress Lab for further experimentation.
Discoveries
Track every compound you have discovered — both verified real compounds from the built-in database and novel syntheses generated by the procedural engine. Your discovery log is saved locally across sessions.
