Molecular surface tension creates the astounding effect of water literally holding its shape on a myriad of surfaces. Due to this dynamic, water globs can even be rolled around on certain materials, making for an enjoyable exercise and sight.
I recently stained and sealed my deck so the coated wood boards and caps had just the right characteristics to create a vibrant scene of sorts. What strikes me is the seemingly simplicity of the water droplets standing on wood, all-the-while the science behind this occurrence is rather complicated.
When I contemplate that all the water which exists in our world will never increase nor decrease I stand amazed at its resiliency to return to the form we know most: liquid. Water can take on the form of ice upon freezing or steam after boiling. It can be found flowing rapidly down a mountain stream or slowly moving along the path of an old river. It can become a torrent of waves during a severe storm and jetted through a fire hose or sprinkler head. Water can be found on a placid lake or in a family pool. It can even cut steel.
Some parts of the world receive less than a cup of water a year while other areas receive so much rain that it can’t be accurately measured. Finally, consider the amount of water which makes up a large part of our bodies, and the bodies of most of God’s creatures. Humans can’t last even two weeks without in-taking water. A rather valuable resource, don’t you think? We sure could use more cohesion among the human population !
