Imagine a siphon that works on its own! Don’t believe it? Try this experiment. Heat a glass tube over the Bunsen burner. Now bend the siphon into the shape shown in the illustration. Put it into a container of water, the tube turns into a siphon that drains off all the water from the container. There are many different self – starting siphons. But this is the simplest of the lot that have been invented. Some of these siphons date back to ancient Greece.
How does it work?
Once the water rushes through the tube to seek it own level, its inertia is sufficient to carry it above Bend B and make the siphon work.
