Christmas Candy Crystal Competition
We loved this Christmas tree crystal grown by Julia Mundy of the John Innes Centre and were delighted to award her a £25 Amazon gift voucher as a winner in our Christmas crystal competition.
There's still time for you to enter and possibly win a prize: just tweet @molecularD or email
us a picture of your crystal by 7th January 2019, and you could be in with a chance of earning an Amazon gift voucher as well!
As a reminder, the Molecular Dimensions children and grandchildren kindly agreed to demonstrate how to set-up a rock candy crystallisation, below.
Many thanks to them, and a merry Christmas and a happy new year to you!
- Clip a wooden skewer to a clothes-peg so that when the skewer is suspended in a jam jar it rests about 2.5 cm above the bottom of the jar.
- Pour a cup of water into a saucepan and bring to the boil.
- If you want coloured crystals, add some food colour. For brightly coloured crystals, you will need to add quite a lot of colouring.
- Add about 1/4 cup of sugar and dissolve completely. Keep adding sugar until no more will dissolve. Be patient and don't stop too soon!
- Pour the supersaturated sugar solution into your jam jar.
- Add your skewer.
- Crystals should appear in 3-7 days.
- Send us your pictures of crystals. We can't wait for them to brighten our new year!
