00:07 Wow! I love the sight of snowflakes.

00:11 Aren’t they the most mesmerizing thing?

00:14 So today, I feel like talking all about snowflakes!

00:19 Zoom in!

00:22 When an extremely cold water droplet comes in contact with dust and freezes on it,..

00:28 ..ice crystals are formed!

00:31 And when those crystals start sticking to each other and falling on the ground,..

00:36 water vapor freezes and sticks on them, building new crystals.

00:42 Therefore, snowflakes are formed during really low temperatures.

00:50 There’s something absolutely remarkable about snowflakes!

00:54 Now, see these two!

00:56 What do you think is different?

01:00 Now, see this.

01:02 And this.

01:04 So, no two snowflakes have the same structure!

01:09 Yes, since every snowflake follows a different path while falling on the ground,..

01:15 ..they experience different atmospheric conditions.

01:19 And thus, they all tend to look different from each other.

01:24 Some look like prisms, while some have a needle-like appearance.

01:29 while some have the familiar icy pattern!

01:35 What do you think is the color of snow?

01:39 White? Blue?

01:42 No, actually snowflakes are colorless!

01:47 That’s because snowflakes are translucent,..

01:51 ..which means that light hardly passes through them and rather gets reflected.

01:57 Hence, this creates a white like appearance in the snowflakes!

02:03 Since, we are talking about appearances…

02:06 I think I should tell you about the smallest snowflake!

02:10 Take a guess, what could be its size?

02:14 No.. No… no…

02:17 Ahaaan! There you go!

02:19 The smallest snowflake could be as small as a human hair.

02:25 And it has a name too.

02:28 The Diamond Dust Crystals.

02:31 They are super rare and appear in bitter cold winter.

02:35 And the largest snowflake till date is…

02:38 Ahaan! You gotta wait for that till Trivia time!

02:44 The largest snowflake observed was 15 inches long!

02:49 Larger than these two pencils put together!

02:53 Each winter in the U.S, at least 1 septillion ice crystals fall on land!

02:59 That is.. 1,000,000,00…

03:08 Actually Its 24 zeros!

03:13 So, you enjoy the feel of snow snuggled up in your blanket.

03:19 With a big mug of hot chocolate.

03:21 and don’t forget to tune in next time for more fun facts.

03:26 This is me zooming out!
