2/$30 Forward-looking Wooden Periscope

Home Depot Kids Workshop Assembled Forward-looking Periscope In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. This sends light directly down the tube and onto the lower mirror. This mirror also at a 45° angle, reflects light directly to your eye. A periscope is a useful example of the law of reflection at work. SALE ITEM: 2 for $30!
