How to make a periscope

Have you ever wanted to explore the world from a different perspective? With a homemade periscope, you can do just that! A periscope is a device that allows you to see objects that are not directly in your line of sight by using mirrors. It’s a fun and educational project that you can easily make at home with a few simple materials.

To make a periscope, you will need the following materials: two small mirrors, a cardboard tube (such as from a toilet paper roll or a wrapping paper tube), a ruler, a pencil, scissors, tape, and a piece of construction paper or cardboard.

The first step is to measure and mark the halfway point of the cardboard tube using the ruler and pencil. Cut the tube at this point using the scissors. This will create two equal-sized pieces of tube, which will be the main parts of your periscope.

Next, take one of the tube pieces and tape one of the mirrors to each end using strong tape. Make sure that the mirrors are angled towards each other, facing inward. This will reflect the light and allow you to see objects from different angles.

How to Craft a Homemade Periscope

A periscope is a handy device that allows you to see over walls or around corners. Although you can buy a ready-made periscope from a store, making one yourself can be a fun and educational craft project. Here’s how you can craft a homemade periscope:

Materials:

Two small mirrors
Cardboard tube (e.g. from a paper towel roll)
Scissors
Glue
Ruler
Pencil

Instructions:

Measure and mark the midpoint of the cardboard tube.
Carefully cut the tube in half at the marked point. You now have two smaller pieces.
Place one mirror at a 45-degree angle inside one of the tube pieces. Use glue to secure it in place.
Repeat step 3 with the second mirror, placing it at a 45-degree angle inside the other tube piece.
Wait for the glue to dry completely.
Attach the two tube pieces together, aligning the mirrors so that they face each other.
Once again, use glue to secure the tube pieces together.
Allow the glue to dry completely before using your homemade periscope.

Materials You’ll Need

To make a periscope, you will need the following materials:

2 small rectangular mirrors
1 cardboard box
Scissors
Transparent plastic or glass
Tape or glue
A ruler
A pencil

These materials can be easily found at a local crafts store or household items you may already have at home.

Step-by-Step Guide

Building a periscope is a fun and educational project that anyone can do. Follow these steps to create your own periscope:

Gather your materials:
- Two small mirrors
- A sturdy cardboard tube
- A ruler
- A pencil
- A craft knife
- Adhesive glue or tape
Measure and mark the center of the top of the cardboard tube.
Cut a small hole, about the size of a quarter, at the marked center using the craft knife.
Position one of the mirrors at a 45-degree angle inside the tube, facing the hole. Use adhesive glue or tape to secure the mirror.
Place the second mirror at a 45-degree angle at the opposite end of the tube, also facing the hole. Secure it with adhesive glue or tape.
Your basic periscope is now complete. Make sure the mirrors are positioned correctly by looking through one end of the periscope and observing the view from the other end.
Decorate your periscope with paints, markers, or stickers to personalize it.
Enjoy using your homemade periscope to explore and view objects that are out of sight!

Tips and Tricks for Better Results

Building a periscope may seem like a simple task, but there are certain tips and tricks that can greatly improve its functionality and results. Here are some guidelines to help you get the best out of your homemade periscope:

1.	Ensure proper alignment of mirrors: It is crucial to carefully align the mirrors of your periscope. Misalignment can result in distorted and blurry images. Use a ruler or measuring tape to ensure that the mirrors are perfectly aligned.
2.	Use high-quality mirrors: Using low-quality or tarnished mirrors can affect the clarity of the images. Invest in good quality mirrors that provide a clear and accurate reflection.
3.	Optimize the angle of reflection: Experiment with different angles of reflection to achieve the best results. Adjust the mirrors and periscope tube until you find the optimal angle that provides the clearest image.
4.	Minimize light leaks: Light leaks can diminish the quality of the image observed through the periscope. Seal any gaps or openings in the periscope tube using tape or glue to prevent unwanted light from entering.
5.	Clean the mirrors regularly: Dust and smudges can affect the clarity of the image. Clean the mirrors with a soft, lint-free cloth regularly to maintain optimal image quality.
6.	Experiment with different materials: While traditional periscopes are made with cardboard, you can try using different materials such as PVC pipes or metal tubes. Different materials may provide different levels of stability and image quality.
