What snack might you take with you when you go rock hunting? Rock candy, of course!
Did you know that you could make your own rock candy (or candy crystals, as they are sometimes known)?
Pour half a cup of water into a saucepan, and bring it to a boil.
Add about a cup of sugar to the water, spoonful by spoonful, stirring so that the sugar completely dissolves.
Keep adding the sugar until it is a clear syrup.
Take care that the syrup doesn’t boil over (have your parents help you, in any case, at the stove).
Let the syrup cool for about ten minutes before carefully pouring it into a glass that has a weighted string hanging in it. (Tie a paper clip to the string for a weight).
This part was easy. Waiting for the crystals to form might be harder.
It will take about a week before there are crystals forming along the string.
Check the glass every day, and carefully break the crust that forms on the top of the syrup, to allow evaporation to continue. The less the solution is disturbed the better the crystal formation will be.
