Our rock candy created this formation
A
crystals
B
granules
C
crumbs
D
pebbles
Explanation: 

Detailed explanation-1: -A supersaturated solution is unstable-it contains more solute (in this case, sugar) than can stay in solution-so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.

Detailed explanation-2: -Crystallization in Candy-Making To make many types of candy, you start by dissolving sugar in boiling water to make a syrup. If you use more sugar than water, as the syrup cools, sugar crystals can begin to form-this process is called crystallization.

Detailed explanation-3: -Rock candy is made by dissolving as much sugar as possible into a pot of hot water, then cooling the sugar-water mixture to initiate crystallization. As the sugar-water cools, sugar molecules will separate out from the water and stick to other sugar molecules, forming solid crystals.

Detailed explanation-4: -Kohakutou is a Japanese candy made from Agar Agar. It is made by pouring flavored jelly into a dish and allowing it to set before cutting or tearing into crystal shapes. The candy develops a crunchy outer crust after a few days but remains delightfully chewy inside.

Detailed explanation-5: -For centuries Rock Candy has been recognized as having marked therapeutic and preservative qualities. In fact, in the West, sugar was used only as a medicine or preservative up to the middle of the 18th century when people “discovered” it made a sweet treat as well.
