Three New Categories
What's Inside
Magic of Physics
We picked eight simulations where physics genuinely looks magical — and gave them simplified controls that a six-year-old can use without a parent. Think: soap bubbles that merge and split, dominoes with chain-reaction physics, sand that flows like water, and a bouncing ball that never seems to lose energy. Each simulation opens with a one-sentence "Did you know?" prompt designed to make children ask "why?" before they even press play.
Space for Kids
Our existing solar system, binary stars, and asteroid deflection simulations were powerful but overwhelming for young learners. We created child-friendly variants with fewer parameters, guided questions ("What happens if you make the star bigger?"), and bright colour coding that makes the physics immediately readable.
Kids Chemistry
The newest and smallest category — five visualisations of molecular behaviour, crystal growth, and chemical reactions. These don't require understanding of the actual chemistry; they're designed to build intuition about how matter behaves at scales too small to see. Coming soon: a "mix the chemicals" sandbox where children can combine simulated substances and watch the reaction.
Design Principles for Young Learners
For Teachers and Parents
We receive a lot of messages from teachers who use our simulations in class. We're adding a "Classroom Guide" PDF for each kids category — suggested questions, learning objectives aligned to curricula, and discussion prompts for group work. The first two (Magic of Physics, Space for Kids) are available in the category pages now.
