Is there a DIY activity that involves light/LED that can capture people's attention to DIY in 10mins?

I would like to begin an innovation class with an activity that catches the attention of the public, but very quick and that anyone can solve, showing that DIY and the maker mindset is for everyone and that it is empowering! I think all people like lights, that's why I thought of LEDs...
