Spending the day at home today =) to get some rest and found a way to have fun, experimenting and playing with the cool phenomena when water condenses into visible droplets evaporating from the cup of tea.
The dynamic-spectrum effect on the left side of M.Soleil reminds me of this amazing encounter of two women in canoe that stumbled across one of nature's greatest phenomenons; a murmuration of starlings : Murmuration by Sophie Windsor Clive & Liberty Smith
Something cool I learned about it :
"The constituent molecules of a vapor possess vibrational, rotational, and translational motion. These motions are considered in the kinetic theory of gases.
The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion. Essentially, the theory posits that pressure is due not to static repulsion between molecules, as was Isaac Newton's conjecture, but due to collisions between molecules moving at different velocities.
While the particles making up a gas are too small to be visible, the jittering motion of pollen grains or dust particles which can be seen under a microscope, known as Brownian motion, results directly from collisions between the particle and gas molecules. As pointed out by Albert Einstein in 1905, this experimental evidence for kinetic theory is generally seen as having confirmed the existence of atoms and molecules." wikipedia
