The riddle
What can fill a room but takes up no space?
Many people first imagine furniture, water, or air. But the answer isn’t a solid object you can carry or stack. Think of something that changes the room without taking up a corner or a shelf.

Light.
Light can illuminate an entire room without occupying physical space like furniture does. It’s a short, satisfying brain teaser to share with friends and family.
