appear and vanish or change as the water evaporates. 

 Diamonds or rubies could vie in color with what the 

 eye can see, and I know of nothing as fascinating as 

 watching the crystals form and grow. No two drops 

 will be the same and they may take only a few sec- 

 onds up to many minutes to form. Sugar is one of 

 the most beautiful crystals of all to watch. With reg- 

 ular lighting you see only the shape of the crystal 

 and not its color. So if you are looking for beauty in 

 color and design polarize the light in your micro- 

 scope and watch the wonderful color changes. Un- 

 fortunately if the camera is picturing its beauty you 

 cannot watch it at the same time as you can with 

 other forms of light. This makes the element of fail- 

 ure greater as one cannot tell when to start or stop 

 the camera or the speed at which it should run, all 

 of which factors should be known. One can watch 

 the drop through a low-power binocular to deter- 

 mine the starting and end of the picture, but only 

 see the crystal form and not its color, so the per- 

 centage of beautiful results may be small. 



As many are not familiar with the term "polar- 

 ized light" a short definition of it will be given. If 

 you read your encyclopedia you will find several 

 pages referring to technical matter and higher math- 

 ematics, but no simple definition of polarized light,
