You may or may not know what a 'howler' is, but for those who don't know, I'll explain. It is quite simply a noise maker. A very good one. It works upon the same concept of a soup can phone, it sends vibrations through the string when pulled, and the can amplifies the vibrations. The video above demonstrates these haunting noises.
I have early memories of my grandma telling me about these little noise-makers. Many stories I've heard about her brother scaring the kids throughout the woods with haunting noises during the night. It echoes quite nicely in an open field, which makes it very good for creeping out your friends. And better yet, it is very inexpensive to make.
