Take a medium-sized, shallow saucepan and pour water into it. Now, add the sugar, vanilla extract, and corn syrup, into it. Place the saucepan on the stove and cook it on medium to high heat. Without stirring, allow it to boil for 10 minutes. As the mixture starts to boil, take its temperature with the help of the thermometer. When it reads 300 °F, take the pan off the heat.
