Since they are inexpensive and difficult to clean, wooden tongue depressors are labeled for disposal after a single use.
Hobbyists and teachers have found a multitude of uses for tongue depressors (sometimes called "craft sticks" or "popsicle sticks") in their projects. Tongue depressors may be used to form so-called "stick bombs".
