Step 1

In a medium saucepan add in the sugar, corn syrup, and water.

Step 2

Insert the candy thermometer and bring to a boil. Stir constantly until the thermometer reaches 300 degrees.

Step 3

Once at 300 degrees, remove from heat and transfer immediately to a baking pan (lined with wax paper or sprayed with nonstick).

Step 4

Allow it to sit until hardened (about 2 hours). Make sure to cover it while it sits.

Step 5

Once hardened lift the pan up and drop straight down to crack the glass. Repeat until you have fragments at a desired size.
