you know the old saying that like people no two snowflakes are exactly alike but is that really true their intricate beauty is so delicate so fleeting it's made them one of nature's

Great mysteries but that incredible complexity actually comes from very simple building blocks high up in the clouds snowflakes begin as water vapor water molecules whiz around bouncing off of

Each other when the temperature cools the molecules slow down and start sticking to one another they form a hexagon six point symmetry the core structure of a snowflake as each one grows it builds on

That basic geometry creating a crystal lattice that's why you tend to find snowflakes with six arms not five not seven from there the variety just explodes the shapes are practically infinite

So what are the chances of finding two snow crystals that look exactly the same in his lab at Caltech physics professor Ken Lee bricht has figured out how to solve that mystery inside a chamber he makes snowflakes from scratch

He starts with humid air and drops the temperature until ice crystals start to form when they get heavy enough they fall he catches them on a chilled plate or he can watch them grow using time-lapse photography

As he boosts the humidity arms begin to extend out from the corners if he cools the air even more branches shoot off the arms lyrics can create a whole batch of crystals on the same plate like these too they're growing in exactly the same

Conditions and look twins but these perfect copies only exist here in the lab outside up in the clouds it's unpredictable the temperature humidity

And air pressure are constantly changing each snowflake takes its own path as it falls to earth and that's solo flight means they all grow a little differently so each one really is unique shaped by its own individual journey through the

World hey guys it's Lauren we've got a few more tiny mysteries for you find out how Rolie polies ventured out from the ocean to conquer your backyard or how just one handful of sand can tell you the history of the entire planet and
