Combine 1 cup of sugar, ⅛ cup of lemon juice, and ⅛ cup of warm water in a medium-sized pot. Turn the heat up high and bring the mixture to a boil. Stir frequently and be careful not to burn it. Reduce the heat to medium, then to low once it starts to bubble. Remove the pot from the heat. Stir until the wax is golden and syrup-like. Pour the sugar wax into a jar and wait until it's cool.
