DIY Periscope

Ever wanted to have SUPERPOWERED eyes to be able to see around corners? 👀 Than this DIY is for you! Join us in building a periscope 😊 A periscope is a device that lets you see over the top of things, such as fences or around corners. First periscopes were used around 1860 in submarines to allow the sailors to see above the water and they are still used today. A simple periscope is just a long tube with a mirror at each end. The mirrors are fitted into each end of the tube at an angle of 45 degrees - so that they face each other. Light is always reflected away from a mirror at the same angle that it hits the mirror so inside the periscope, light hits the top mirror at 45° and reflects away at the same angle. The light then bounces down to the bottom mirror. When that reflected light hits the second mirror it is reflected again at 45°, right into your eye. Now that you know how a periscope works gather the materials and start building and HAVE FUN! And don’t forget to tag us or send us a picture of your creations to [email protected] to receive a code for a free Open Studio Session for when we are back open again.
