This is a very innovative siphon. Here you can see water being drained out. You will need a transparent plastic glass, two straws, tape etc. Make a small hole in the base of the glass and press fit a stiff fruit juice straw in it. There should be no leakage from the joint. Fill the glass to the top with colored water. The water above the straw will drain out. Water will remain until the top level of the straw. How to drain the remaining water? Now take a 5-cm fat transparent tube. Tape one end and cut a V notch in the other. Cover the straw with this transparent tube and add some more water to the glass. Now some water will enter the straw and this will start the siphon and drain out all the water!

Now fill the glass with colored water but slightly below the height of the straw. Now fill the transparent straw with water and insert it on the straw. This will start the siphon and all the water from the glass will be drained out. This work was supported by IUCAA and Tata Trust.
