Liquid/Surfaces Experiment

Droplets (60^o):

·         Water

·         Ethanol

·         Extra Virgin Olive Oil

Surfaces:

·         Aluminum Foil (flat side)

·         Wax Paper

·         Ceramic Casserole Dish (bottom)

Dropped from a height of 6”

Droplets measured in centimeters



To report my findings:

On the wax paper surface, the different liquids had the greatest height and smallest width. I expected this do to the prior knowledge of water and wax/lipids reaction of repelling one another. The ceramic casserole dish came next with each of the droplets about 0.3cm larger than on the wax paper. The results for the aluminum were quite interesting. While the water stayed similar to the ceramic, the olive oil flattened a bit more. The most unexpected was the ethanol to aluminum attraction. The ethanol became almost entirely flat and spread far out.
