If you live in an area where icicles form in the winter, you know that icicles are normally clear and beautiful. There are two things that make icicles so perfect:

  • Icicles are made from pure water in the form of melted snow. It's de-mineralized water.
  • Icicles are created in layers. Water drips down the icicle and freezes in progressive layers rather than being frozen all at once. This approach avoids the entrapped bubbles.
