Specifically sugar crystal falls under the categorization of isometric, cubic crystal. Crystals are solids that have regularly ordered and repeating patterns of atoms, molecules or ions in three spatial dimensions. This is when our crystals form layer by layer, molecule at a time. It must let go of the extra solute and this in combination with the water evaporating gives us our precipitate (the rock candy). It does this because the super supersaturated solution has too much solute (sugar in this case). While you wait, pour the remaining sugar on a plate. Allow the mixture to cool for 20 to 30 minutes. ![]() Add 3-7 drops of food coloring and/or flavoring to the mixture if desired. Remove from heat once the sugar has dissolved. Try different color combinations or even try adding flavoring to your crystal candy!Īs the sugar solution cools it becomes supersaturated, so it starts to changed from a liquid to a solid. Add the sugar, one cup at a time, stirring throughout. ![]() Wait and watch your crystal candy grow! (It should take about a week) If your string keeps sticking to the sides try using a paperclip to weight the end.Ĩ.Set jar aside somewhere it will not be disturbedĩ. Place pencil with yarn across the jar with string dangling in. Pour solution into jar (try to keep undissolved sugar in pot)ħ. Continue adding sugar until it will no longer dissolve.Ħ. ![]() ![]() Measure and cut yarn to hang in jar without touching sides or bottomĤ. Your Challenge: Make rock candy by growing your own crystals!Ģ.
