Question 32171: One evening, a husband and wife are working in their garden. While watering the grass, the wife holds the hose horizontally and the water flows from the end of the hose.She twists the nozzle of the hose to partially close it and suddenly the water shots father from the end of the hose. This seems odd to her husband, who wondrs, "why does the stream of water travel farther, since it appears that less water is flowing from the end of the hose?"
Your challenge is to give a scientific explaination for this seemingly unnatural phenomenon. ????
