Soft ball stage is a test used to check on the readiness of syrup. You do this by pouring a few drops of the solution into a saucer filled with cold water. And then you try pushing it with your finger. If the syrup dissolves immediately, the syrup is not ready. Boil it a little longer and test again. At soft ball stage, the solution can be molded into a very soft ball with your fingers. An easier way to determine the soft ball stage is by using a candy thermometer. Soft ball stage is when the solution reaches between 235 to 240 degrees Fahrenheit or between 112 to 116 degrees Celsius.
