Description
A wonderful macro image of Oil and Water with a colorful background. I then added effects to get a Georgia O'keeffe painterly look.
There is sevral things you can do or should I say play with to get different effects. Make a home-made lava lamp by filling a jar two-thirds full of water and put in some food colouring. Add some cooking oil. The oil will float on top of the water. Shake some salt onto the oil � it will form a blob and sink to the bottom. Once the salt dissolves, the oil will float back up to the top. If the oil doesn�t sink, sprinkle on a bit more salt.
The oil floats on top of the water because it is less dense (a spoonful of oil weighs less than a spoonful of water). The salt is denser than the water � it weighs the oil down and makes it sink. Once the salt dissolves in the water, the oil floats back up to the top of the water.
Make a glitter globe by filling a jar one-quarter full of surgical spirit, and then almost filling the jar with cooking oil. Drop in a few sequins and some glitter, or other small shiny things. Fill the jar right up to the brim with oil, and screw the lid on tightly. Shake the jar. The oil and alcohol will mix together and then separate, and the glitter and sequins will sparkle as they move around in the mixture.
The alcohol floats on top of the oil because it is less dense (a spoonful of alcohol weighs less than a spoonful of oil). Like water, alcohol is a polar molecule so does not mix with oil.
