A Bell System
You can make a bell system that actually works. How loud it would be and how does it look like, depends on your creativity and plans. It involves an electromagnet that you can simply make it using a battery, some insulated copper wire and a steel pin or nail.
Your display can include a drawing of a bell system and a working bell system that everyone can test.
