There are 1.648×10^23 molecules in 1 tsp (4.929 ml) of water. There are three atoms in a single molecule of water, meaning there are a staggering 4.943×10^23 atoms within a single teaspoon of water.
This means there are more atoms held in that teaspoon than there are stars in the universe (3×10^23 stars, according to research published in 2010 by Pieter G. van Dokkum and Charlie Conroy).
The volume of the Pacific Ocean, according to the NOAA National Geophysical Data Center in 2010, is 1.339×10^23 tsp, which is significantly less than the number of atoms in a single teaspoon of water.
I’m amazed that within something as seemingly insignificant as a teaspoon of water, there might as well be an infinity of atoms. Those atoms can themselves be broken down into subatomic particles which can be broken down still into tinier objects still, such as gluons.
The mind boggles.
