Tuning forks are wonderful tools for teaching physics. Every physics classroom should have several and every physics student should be taught how to use them. In this article, I highlight 10 enriching demonstrations that most teachers might not know, as well as provide tips to enhance the demonstrations teachers might already be doing. Some of these demonstrations have appeared in literature before, but this paper will serve as a collection of ideas that will be helpful for both the beginner and master teacher. (Contains 2 tables and 11 figures.)
