Spy on what’s going on underwater with your own underwater scope. Make one with these instructions from the Get Outside Guide by Nancy Honovich and Julie Beer.
Using a can opener, cut the end off of an empty coffee can so both ends are open.
If you want to add color to your can, cut a piece of construction paper to fit the size of the coffee can all the way around. Then glue it on.
Cut a large piece of plastic wrap and cover one end of the can. Secure the plastic wrap with a heavy-duty rubber band. Place the scope in the water with the plastic wrap side facing down and take a look at whatever decides to swim by!
If you want to make a scope for deeper water, follow the same steps but use a longer piece of PVC pipe in place of the coffee can!
