Happy mole day!

Tomorrow, October 23rd, we will celebrate the "Mole day", starting at 6.02 AM till 6.02 PM. This celebration relates to Avogadro's number which is approximately 6.02 x 10²³. The National Mole Day Foundation organizes activities for this day. The theme for this year is the Molar Eclipse.
Below, you have a video "A mole is a unit". I hope you will enjoy it.

Happy mole day to you!
