Little kids love to get down and dirty and see what's going on with nature ... especially if it involves getting wet.  This Earth Day, encourage your kids to do just that with an underwater viewer you can make from the items in your recycle box.  Here's how it's done:

 

 

Using a can opener, remove both ends from your extra large can, making sure that there are no sharp edges remaining.  Stretch the plastic wrap over one end of the can and fasten securely with duct tape.  Voila!  An underwater viewer perfect for exploring the fish, rocks, and marine life in your favorite pond, river or stream.
