At Popular Science, we report and write dozens of science and tech stories every week.

And while a lot of the fun facts we stumble across make it into our articles, there are a lot of other weird facts that we just keep around the office.

We've figured why not share those with you? Welcome to the weirdest thing I learned this week from the editors of Popular Science. I'm Rachel Fultman.

I'm Claire Malderilline, and I'm Sarah Trudeau.

On the weirdest thing I learned this week, we start out by each offering up a little tease of something we've picked up, either while reporting, reading other people's great reporting, editing, wasting time on Twitter, talking about weird stuff, etc.

And we decide which one we just absolutely have to hear more about first. And then once we've all had time to spin our little science yarns, we reconvene and decide what the weirdest thing we learned this week actually was.

And as always, if you agree or disagree with our verdicts, you should let us know on Twitter at WeirdestUnderscoreThing or hashtag WeirdestThingPod.
