Try this periscope activity and turn an empty waxed paper box into a spy tool for looking around corners, over walls and out of windows. If you enjoy easy crafts, then this fun periscope activity is ideal!

What You'll Need:

  • Empty waxed paper box
  • Scissors
  • Masking tape
  • Two small mirrors (about two by three inches)

How to Make a Periscope:

Step 1: Ask an adult to cut off the cutting edge of the box. Tape the box closed with masking tape. Cut out a small square on the top end of one side of the box.

Step 2: Cut another small square out at the bottom end of the opposite side of the box. On a third side (a side between the two sides with the cutout holes) cut a diagonal slit at each end of the box.

Step 3: Cut each slit so that the bottom of the slit is level with the bottom edge of one of the cutout squares, and the top of the slit is level with the top edge of the cutout square. The bottom slit's bottom should be close to the cutout hole and slant away from the hole. The top slit should slant in the same direction as the bottom one.

Step 4: Cut identical slits on the opposite side of the box. Each slit should be a little bit wider than the mirror width so the mirrors will fit in the slits.

Step 5: Slide a mirror into each slit. If the mirrors are one-sided, slide them in so the reflective sides face the holes. Secure the mirrors in place with tape.

Hold the periscope upright, and look into the hole at the bottom. You'll see what's caught in the reflection from the top hole!
