All right. How about the longest time spent in full body contact with snow? So that would be 105 minutes and two seconds.

How about the most people making snow angels simultaneously? So that one is 8,962 people who gathered in North Dakota. And then there's the largest snowflake. So the Guinness people say there was a snowflake 15 inches in diameter and 8 inches thick. that fell in Montana in 1887.

I mean, come on, that is a big snowflake. And what I learned is that, you know, first of all, you have to make it clear what you mean by the word snowflake. And I recently talked to a couple of scientists about that. One of them is Kenneth Librecht. He's a physicist at Caltech. And that particular Guinness World Record has always kind of bugged him.

So he told me that just this past year, like six months ago, he decided to do something about it.

He really made a name for himself making snowflakes in the lab. Or as he would point out, he actually makes snow crystals.

I mean, when I say snowflake, do you imagine something that looks sort of like those snowflakes that people cut out of like white folded pieces of paper with scissors? Yes, absolutely, that six-fold symmetry. So that kind of snowflake is really a single ice crystal.

But a flake can also mean these big puffballs that fall from the sky that are actually many, many tiny snow crystals that have gotten sort of tangled up together. And that's why the Guinness World Record for the largest snowflake really bothered Kenneth Librecht. He says it's got to refer to that kind of puffball, but... When people hear the world's biggest snowflake,
