Welcome to Science Buddies!

Just to let you know, rock candy projects might take as long as 10 days from start to finish. Meanwhile, you can take note everyday on a data table of your progress.

I would suggest you to review all the procedures found on the link, http://www.sciencebuddies.org/science-f ... #procedure, which gives an excellent project overview for your rock candy experiment.

For your reference, http://www.sciencebob.com/experiments/rockcandy.php gives a great explanation of how the rock candy forms: "When you mixed the water and sugar you made a super saturated solution.This means that the water could only hold the sugar if both were very hot. As the water cools the sugar "comes out" of the solution back into sugar crystals on your skewer. The skewer (and sometines the glass itself) act as a "seed" that the sugar crystals start to grow on."

Good luck!
