Dazzling crystals



Have fun growing a dazzling crystal with this 4M crystal growing kit from shop.australiangeographic.com.au. You will be amazed as you learn the chemistry and formation of crystalline structures. But as it takes 10 to 15 days for your crystal to grow, you will have to be patient.

For your chance to win a crystal-growing kit, study the pattern in this photo and send us a drawing of what you think it is.
