My favorite experiment. Quick and easy and very impressive way to illustrate the influence of temperature on water densities.
Today in the “introduction to oceanography” (GEOF130) we conducted my favorite experiment ever:
Cold water in one of the small bottles is dyed blue, hot water in the other small bottle is dyed red. Both are inserted in a jar filled with lukewarm water (movie below). Isn’t this beautiful? And you just wait until we add salt into the equation (and the water) next week!
