To make a periscope, you can follow these steps:
1. Find two small mirrors the same size and a cardboard box or a piece of cardboard.
2. Cut the cardboard into a tube shape and make holes for the mirrors at each end.
3. Insert the mirrors facing the holes at a 45ยบ angle and tape them down.
4. Decorate the periscope with paint or duct tape if desired.
You can also use PVC pipes instead of cardboard to make a more durable periscope.
