How can you see what’s going on in the water without diving in? Use an underwater viewer!
You can make a very simple underwater viewer with materials you already have at home. All you need is a half-gallon milk carton, some clear plastic wrap and a rubber band or some tape.
- Cut both the bottom and the top off the milk carton.
- Stretch the plastic wrap over the bottom, securing it in place with a snug-fitting rubber band or some tape.
- Lower the viewer into the water, and place your face into the open end of the milk carton.
The underwater area you are viewing will be slightly magnified. It’s very much like a diving mask, only you don’t have to get your face wet to use it.
