Turn your whole chalkboard into a speaker!
This music box mechanism is quiet in its plastic case, but remove it from the case and hold it against a large object (table, chalkboard, window, paper cone, drum) and hear a dramatic increase in volume! It's a simple but memorable demonstration of how sound energy transfers through the process of resonance.
