Super Short Straw Projects: Duck call

The next project I saw promised to make loud noises, so I gave it a whirl. This post shows you details for how to make a duck call from a straw, but all you need to do is cut one end into a point and blow fairly hard into that end of it. And it does make a satisfyingly loud duck-like call or sometimes squeal.

Take it further by having students experiment with different kinds of cuts or different sizes or types of straws.
