How to celebrate the nerdiest holiday this side of Pi Day

Today is National Mole Day. Because if there's any occasion to recognize the breakthrough number that is 6.02214179(30) × 10^23 -- and the breakthrough unit that serves as a bridge between the microscopic and macroscopic worlds -- it is, obviously, 10/23. Between, obviously, the hours of 6:02 am and 6:02 pm.

For those of us who are neither chemists nor physicists, Avogadro's number is generally something we learned about in high school. Generally, from teachers who made "no, not that kind of mole! Or that kind of mole!" jokes in the process. So while the official theme of this year's Mole Day -- as determined by, yes, the National Mole Day Foundation  -- is "Molar Eclipse," let's celebrate in a way that will pay tribute to those joke-cracking educators. Today, on the nerdiest holiday this side of Pi Day, let's celebrate the mole from the point of view of the high school chemistry class. 

The video below comes from a teacher. The video below that comes from students. They both come from a place of nerdy wonder. Enjoy. And happy Mole Day.
