Connected by water

Someone asked about the story I told in the water communion service this past Sunday. Here it is:

Each year we do this water communion service. When we share our water in the common bowl, it symbolizes that while we are separate people, we are also part of an interdependent community.

You probably know about the water cycle. When it rains, water falls from clouds onto the ground, and eventually it flows into a river, and all rivers flow down to the ocean. Water evaporates from the ocean and forms clouds, the clouds drift over the land, it rains, and the cycle begins again. You’re in the middle of this cycle because you drink about 2 liters of water every day, and then you sweat or urinate and put water back into the water cycle. So water is constantly on the move.

You probably know that water is made up of molecules, and that each water molecule is made up of two atoms of hydrogen and one atom of oxygen. Water molecules are incredibly tiny, so tiny you cannot see them. If you had 18 grams of water, or a little more than half an ounce, that would be about 6 x 10^23 (pronounced: “six times ten to the twenty-third”) molecules. The molecular weight of water is approximately 18, and therefore 18 grams of water should have a number of molecules equal to Avogadro’s number, or 6.02 x 10^23.

This is a fairly large number. I can show you what this number would look like. We’ll start with six hundred and two:

602

Add six zeros to get six hundred and two million:

602,000,000

And this would be six point zero 2 time ten to the twenty-third:

602,000,000,000,000,000,000,000

or 602 sextillion. [When I told this is the water communion service, I had this number printed out, and it was so long several people had to help hold it up.]

If you’re a child who weighs about 77 pounds, or 35 kilograms, then you have about 20 liters of water in your body (adults, you can multiply up to figure it out for yourselves). That’s approximately 20,000 grams of water, or 6.02 x 10^26, or 602 septillion, molecules of water in your body if you’re a child. And if you drink 2 liters of water a day, you’re replacing about ten percent of that, or 6 x 10^25 molecules, each day. So if you are 3,650 days old (that’s ten years old), about 2.2 x 10^28 water molecules have already passed through your body. This is an even larger number, and here’s what that number looks like:

22,000,000,000,000,000,000,000,000,000

[When I told this story at the water communion service, I had this number printed out, too, and it took even more people to hold it up!]

Because water is constantly cycling around, and because every human being has such large numbers of molecules of water cycling through them, there’s a very good chance that each one of us has at least a few molecules of water that were formerly in the body of Socrates, the great philosopher. We each probably have some molecules of water that were once in the body of Jesus of Nazareth, and of the Buddha, and any number of great and wise people who lived in the past.

Thus when we say that we are all interconnected, that statement is quite literally true — we are all interconnected through the water cycle, not only with each other, but with all living beings past and present. Jesus, Confucius, Ralph Waldo Emerson, Eliza Tupper Wilkes — she was the first Unitarian minister in Palo Alto — you might be literally connected with each of these good and wise people.
