How does a submarine find objects above water? How can you peer through walls?

Introduce kids to the wonders of Optics with Smartivitys Periscope. A periscope is an instrument for observing over, around, or through an object by using mirrors aligned in a particular pattern so that images are reflected multiple times and carried to the viewer without exposing the viewer. Get ready for your adventure! Once the periscope is assembled, build the ship, place it on any high surface, and use the periscope to locate the ship from below!
