Einstein, Newton and Pascal decide to play hide...
Pascal is no where to be seen. Newton is sitting right in front of Einstein, with a piece of chalk in his hand. He’s sitting in a box drawn on the ground, a meter to a side. Einstein says “Newton, you’re …terrible, I’ve found you!” Newton says “No no, Einy. You’ve found one Newton per square meter. You’ve found Pascal!”

Solubility Rules (submission)
The closest tune I can think of that this song is sung to is “99 Bottles of Beer on the Wall.”
I’m missing a verse, but other than that, each verse covers all the solubility rules.
All letters and numbers are said out, for example: C2O2H3 is read “see-two-oh-two-eightch-three”
