Even on an overcast day, it is hard to see into a tide pool or pond. That’s because any body of water has a “skin” on it, molecules of water on the surface that adhere more closely to each other than molecules beneath the surface. The result is that light bounces off this top layer, making it difficult to see further down. But an underwater viewer bypasses this problem by slipping beneath the water’s “skin” and blocking out reflected light. This easy-to-make device is a great way to explore the wonders of aquatic life.

This is an optional step and not necessary for the viewer to work. Attach plastic wrap to one end of the can. Make sure the wrap is pulled taut. Use a thick rubber band to hold the wrap in place.
