Saying "Avogadro's Number" Avogadro's Number of times.

Avogadro's Number is 6.022140857 i- 10²³. That's how many atoms are in 12 grams of carbon-12. One mole of anything has one Avogadro's Number of elementary particles in it. In this video, the Action Lab Man repeats the words "Avogadro's Number," quadrupling the audio track each time until he reaches 6.022140857 i- 10²³. Each time he utters the words, he includes an interesting fact about the in-progress number. For example 256 is the "Unplayable/unbeatable level in Pac-Man due to an 8-bit integer overflow." And 68,719,476,736 is the "Number of animals eaten by humans each year."

He ends the video by describing what would happen if you gathered together a mole of moles, as found in Randall Munroe's great book, What If? Serious Scientific Answers to Absurd Hypothetical Questions.
