This photo was taken on a Canon EOS 5D camera. This experiment is a visualization of the density of different common household liquids. The three liquids in the glass are dish soap, water, and olive oil. Dish soap was poured on top of the olive oil. As the dense dish soap travels through the olive oil, some of the oil becomes trapped in the parcel of soap as it sinks. This leads to streaks of oil and green passing through the water towards the bottom of the glass, resulting in the green liquid visible in the water.
