Fun at home science demonstration about the polarity of liquids. Oils (non-polar) liquids will naturally separate from Water (polar). And if you dye the water you get a "bottled ocean".
Be careful with paint thinners and other light oils, their fum...es are flammable. Do not swallow, etc. Because that would be SMRT.
