Reactorium: Chemistry Lab

Welcome to your very own chemistry lab! In Reactorium you drop atoms from the complete periodic table into a flask, mix them and discover real chemical compounds and reactions – with the correct formula and a balanced chemical equation.

🧪 HOW IT WORKS
• Tap an element – every tap adds one atom to the flask.
• Pick a condition: normal, heat, light or electricity (electrolysis).
• Mix! 2 H and 1 O make water, 2 H and 2 O make hydrogen peroxide – the ratio is what counts.
• Put your discoveries back into the flask and let them react: acid + base, CO₂ + water, sodium + water and much more.

⚗️ REAL CHEMISTRY
• All 118 elements with atomic number, atomic mass, group, period and state of matter
• 241 compounds to discover – from water and table salt to sugar, caffeine and high-tech materials
• 113 real reactions such as photosynthesis, the oxyhydrogen reaction, thermite and electrolysis
• Every equation is balanced, every formula is correct
• Short, easy-to-understand explanations for every substance and reaction

✨ BEAUTIFULLY CRAFTED
• 3D Erlenmeyer flask with realistic substance colors, bubbles, glowing heat, sparks and light effects
• Ceramic-style periodic table with 3D touch and haptic feedback
• Optimized for phones and tablets

📚 COLLECT & LEARN
• All your discoveries are saved in your collection
• Undiscovered compounds reveal which elements they contain – can you find the right ratio?
• Hints help you when you get stuck

Perfect for students, teachers and anyone who loves science. Learn chemistry through play – safely and without any chemicals.
