If you have a pond or creek nearby, you know that watching underwater life can be fun for kids. But surface reflection and glare can make it difficult to see what lurks underneath. An underwater viewing scope will help you see.
This underwater view-scope is made of a container, plastic wrap, and a few other common household items. In addition to reducing the glare on the surface, the pressure of the water on the plastic wrap forms a concave lens, so it also provides some magnification.
Underwater Viewing Scope
- A large cylindrical container – plastic ice cream pail, coffee can, etc
- Plastic wrap
- Large rubber band
- Duct tape
- Cut off both ends of the container, if necessary, so you just have a cylinder left.
- Cover one end of the cylinder with plastic wrap.
- Hold the wrap in place with the rubber band.
- Now attach duct tape completely around the edges of the plastic wrap. You want a very good seal.
- At this point, you can remove the rubber band if it is still free. If you covered it with duct tape, don’t worry about it.
- If you cut the other end of the cylinder, it might have some rough edges. Cover those with duct tape also so you don’t cut yourself.
- Insert the wrapped end of the cylinder into the water and examine the underwater creatures and their habitat.
