Whether you’re a child of the 80s or 90s & have already had a go or are currently a crystal virgin we think these Grow Your Own Crystals are pretty awesome. The idea is simple yet also wonderfully scientific. Take your seed crystal, pop it in a suitable container, dissolve your ammonium dihydrogen phosphate & potassium phosphate power in hot water, let it cool & let the magic happen as your new crystals gather on the seed. We delved into the exciting world of crystal production as children & were proud of our self-made masterpieces. That proudness was switched for crossness as our work gathered dust & was confined to the dustbin by our clean freak mothers. & that’s we think it’s about time we got hold of a Grow Your Own Crystals set & create something quite amazing to adorn mums windowsill forever more.
