<v Speaker 1>Welcome to brain Stuff from house stuff works dot com

0:00:22.520 --> 0:00:33.240
<v Speaker 1>where smart happens. Hi Am Marshall Brain with today's question,

0:00:33.600 --> 0:00:37.000
<v Speaker 1>how do you make clear ice cubes? If you live

0:00:37.040 --> 0:00:39.800
<v Speaker 1>in an area where icicles form in the winter, you

0:00:39.880 --> 0:00:43.360
<v Speaker 1>know that icicles are normally clear and beautiful. There are

0:00:43.400 --> 0:00:47.440
<v Speaker 1>two things that make icicles so perfect. First, icicles are

0:00:47.440 --> 0:00:50.120
<v Speaker 1>made from pure water in the form of melted snow,

0:00:50.640 --> 0:00:54.920
<v Speaker 1>and second, icicles are created in layers. Water drips down

0:00:54.960 --> 0:00:58.680
<v Speaker 1>the icicle and freezes in progressive layers rather than freezing

0:00:58.720 --> 0:01:02.240
<v Speaker 1>all at once, the approach of voids and trapped bubbles.

0:01:02.760 --> 0:01:06.199
<v Speaker 1>If you ever look inside a restaurant ice maker, you'll

0:01:06.240 --> 0:01:09.640
<v Speaker 1>find that it makes ice and layers. Also, cold water

0:01:09.760 --> 0:01:12.959
<v Speaker 1>runs continuously over a plate or a grid where the

0:01:13.000 --> 0:01:16.440
<v Speaker 1>ice is forming, and the ice cubes or ice discs

0:01:16.480 --> 0:01:19.880
<v Speaker 1>in some machines grow in layers. If you would like

0:01:19.959 --> 0:01:23.520
<v Speaker 1>to try creating clear ice at home, start with distilled

0:01:23.520 --> 0:01:26.800
<v Speaker 1>water to eliminate any minerals, and then boil it to

0:01:26.880 --> 0:01:30.640
<v Speaker 1>eliminate air dissolved in the water. Make the cube small

0:01:30.920 --> 0:01:33.720
<v Speaker 1>or thin to get closer to the way that icicles

0:01:33.720 --> 0:01:37.399
<v Speaker 1>are formed. Do you have any ideas or suggestions for
