Hi Am Marshall Brain with today's question,
how do you make clear ice cubes? 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. First, icicles are made from pure water in the form of melted snow, and second, icicles are created in layers. Water drips down the icicle and freezes in progressive layers rather than freezing all at once, the approach of voids and trapped bubbles.
If you ever look inside a restaurant ice maker, you'll find that it makes ice and layers. Also, cold water runs continuously over a plate or a grid where the ice is forming, and the ice cubes or ice discs in some machines grow in layers. If you would like to try creating clear ice at home, start with distilled water to eliminate any minerals, and then boil it to eliminate air dissolved in the water. Make the cube small or thin to get closer to the way that icicles
are formed. Do you have any ideas or suggestions for this podcast? If so, please send me an email at podcast at how stuff works dot com.
