A quick vid showing how easy it is to make a whistle using an Elder stem. Of course, it's then got to make a sound! That can take a little time and a few (many) adjustments, but on the plus side, you can create anything from a piercing scream to an owl hoot! Have fun!
We use these with kids who are learning knife skills for the Wild Passport; here's a link but you can also get in touch with us if you are interested in Wild Passport Instructor Training (we deliver in the North of England), by emailing [email protected]. https://www.wildpassport.co.uk/?msclkid=c4f0b25ba63211ecb1ab6b3d0c622195
