NatHub

Explore waves, light, sand, and magnetic fields through quiet touch-based experiments.

NatHub is a quiet interactive lab for observing natural phenomena through touch. It turns waves, light, sand, and magnetic fields into small experiments you can explore on your device.

The launch version includes four local experiments:

• Water Ripples: tap to watch waves form, spread, and overlap.
• Light Refraction: move glass shapes and observe how light bends and separates.
• Sand Traces: draw through black and white grains and watch each line leave a soft trace.
• Magnetic Array: drag a magnet and see steel needles align into visible field patterns.

NatHub requires no account, includes no advertising, uses no third-party analytics, and has no paid unlocks in the launch version. Experiments run locally on the device, making the app suitable for quiet observation, visual exploration, and an intuitive first step into physics concepts.
