Using an awl or drill, punch three similar holes in an empty plastic milk jug at three different heights. Plug the holes and fill the jug with water.
a. Placing the jug at the edge of the sink, unplug the holes and let the water flow out. Which hole produces the greatest initial speed for the emerging water?
b. Which stream travels the greatest horizontal distance? What factors determine how far the water will go horizontally?
c. Observe the shape of the water streams as they fall into the sink. Do the streams narrow as the water falls? If so, how can this be explained?
