Grow one large "Citrine" crystal cluster and proudly display it on your DIY multi-colour LED display. Assemble your own multi-color LED base. Make a small electrical circuit and connect your LEDs to the base, learning about anodes and cathodes of LEDs. Then, grow one sparkling “citrine” crystal cluster on your multi-color LED base. Watch the magical crystal glow at night! Growing SPACE AGE CRYSTALS is not long or complicated. Just dissolve the pre-mixed crystal powder in warm water, within hours sparkling crystals will start to grow right before your eyes. A fascinating experience for children and adults.
