A simple and interesting wooden whistle can be made from two round blanks, for example, from a handle for a shovel or a tree branch. To work, you will need a drill, two pieces of twig and a sharp knife. One of the mandatory conditions for making a whistle is that the wood must be dry. Otherwise, when drilling a hole, it will turn out to be fleecy, and it will not make sounds.
All gaps must be filled with glue. Give the whistle to dry. Now you can try to blow the whistle. If the hole, which is called the “sound chamber”, is clean and smooth, then the wooden whistle will make a loud whistling sound. Well, if there are a lot of villi, then it will not whistle. In this case, you will have to wait until the musical instrument is still dry and then clean the inner surface.
All your whistle is ready and you can whistle.
