Concentration gradients in a thin layer Tia Maria due to evaporating ethanol cause solutal convection currents. These currents are then visualized by a small amount of coffee creamer. The whole experiment takes place in a glass dish that is lit from underneath.

Travis, this is a super cool picture, I made the comment during your presentation that this sort of looks like a peach. I am also getting hints of sunset colors. How many takes did it take you to get a video you were satisfied with?
Awesome Visuals! I enjoyed how the liquids created such beautiful visuals. I also think you edited it very well, creating great contrasting colors!
