Its huge, glittering eyes stare at you. Its big mouth opens and closes, opens and closes. But suddenly it swims to the other side of the bowl. And it’s only a goldfish after all.
The bowl filled with water acted as a lens. The curved bowl bent the light that bounced off the goldfish and came through the bowl. This made the goldfish look much bigger than it really is.
Anything – even a drop of water – can be a lens if it is curved and if light can pass through it. A curved shape makes light bend and spread. And spreading the light that bounces off something makes that thing look bigger. A lens with the right curve will make something look larger or closer than it really is.
A magnifying glass is just a single lens with two curved sides. You can use it for a close-up look at things like paper, cloth, or even your finger. Move it closer and then further from the object you are looking at. You will get a sharp, clear view, and you may be amazed at what you see!
