You can hear the children tooting away their whistles. You can make a similar whistle using a fat straw, tape and scissors. Cut the fat straw in half. Make a small V cut in only one side of a straw. Make two cuts to form a small flap.  Lift the flap at the back. Make a small circular hole in the center of the other piece of straw. Now place the V part of the first next to the hole of the other. Fold the flap and tape it to the first straw. The taping of the flap keeps both straw pieces together. See that the second piece is hinged and can move. Now as you blow air strikes the circular hole and begins to vibrate making a shrill whistle sound. 
This is a traditional Bamboo Whistle. By blowing from the thin end you can produce a very nice whistling sound!!
