You have a Basket with five identical balls of different colours and you are to pull out (draw) a ball without looking at it, list the outcomes you would get.

Take a table - tennis ball and make three slits into it. put semicircular fins cut out of a metal sheet into these slits.

Direct a jet of water or steam produced in a pressure cooker at the fins. What do you observe ?
