Actually do this way- take some salt water, preferably add some color. Then gently pour fresh water along the sides or with the help of a spoon. The salt water will stay at the bottom and the fresh water on top.Yes very simple, bring glass of water, fill it to the middle with fresh water, then add salt water to its full,
now according to the experiment, the fresh water will float and the salt water will sink.
Try it and see if you can suck fresh water from the top.
Some restaurant people make use of this principle to serve layered drinks. It will look like one layer of liquid is stacked on top of another.
