What did Josh do that allowed him to dissolve that much sugar in only 100 g of water?

Heating water increases how much sugar can dissolve in it, so Josh could dissolve a larger amount in only 100 g of water. Stirring or using a larger surface area can help sugar dissolve faster, but they do not increase the maximum amount that dissolves at a given temperature. Sugar cubes would generally dissolve more slowly than granulated sugar.
