This experiment can be very time-consuming, because giant crystals do not
grow readily. They tend to break off into small crystals. Therefore, you must
repeat the experiment over and over beforeobtaininga satisfactory result.
But you will find it wellworththe time and patience required. Scientists are
amongthe mostpatientpeople on earth.
