Wikijunior:Big Book of Fun Science Experiments/Periscope

Do you like spying? If you do that's very good. We are going to make a periscope today.

You will need:

  • 2 small mirrors
  • Sticky tape
  • Scissors
  • Rectangular box


  1. First, cut out a hole just big enough to fit the mirror into the bottom of one side.
  2. Then do the same on the top of the other side. Place the mirrors into the holes so that they fit snugly in the corner, and use the tape to keep them there.
  3. When you look through one hole, you should see out the other hole.
