Thames and Kosmos Crystal NightLight
Ready to grow a beautiful crystal and make it into a cool nightlight that will glow in a spectrum of colours? First grow the crystal from alum powder, then wire up the nightlight circuitry. Put the crystal onto the special platform and switch on. The colour-changing LED will light up your crystal!
