Play N Learn Big Bang Science Magic Crystal Kit | STEAM Crystal Growing Experiment

🎯 What It Does

Turn a small tabletop tank into a living underwater garden of crystals. Drop the magic rocks into the sodium silicate solution and watch delicate, colourful spires push upwards from the base — the first shoots appear within roughly 10 minutes, and the formations keep climbing to as tall as 10 cm over about two hours. Set against the outer space background card, the growing crystals look like an alien landscape unfurling in slow motion behind the glass.

🌟 Why It's Great for Learning

Crystal growing makes chemistry visible. As the metal salts in the rocks meet the sodium silicate, they form a thin semi-permeable membrane that swells, ruptures and reforms — driving the branching, coral-like towers upwards in a process known as a chemical garden. Young scientists observe supersaturation, precipitation and osmosis unfolding in real time, and the two-hour growth window is ideal for practising careful observation, timing, sketching and recording results across a single session.
