Learn how to make a periscope and understand how a periscope works. • • Periscope is used to see objects which are not at the same level as of observer. Light from the object falls on one mirror and is reflected. This reflected light in turn falls on another mirror and is again reflected until it reaches human eye. It lets you see over the top of things such as fences or walls that you aren't tall enough to look over. People first started using periscope in submarine to allow sailors to see above the water. • #periscope • Thanks for watching! • SUBSCRIBE to our channel • / beeamaker • Don't forget to give us thumbs up • • ************************************ • FOLLOW Bee-a-maker on • Facebook • / bee-a-maker-2099988586755017 • Instagram • / bee.a.maker • Pinterest • / bee_a_maker • ************************************ • Watch our other videos • Parachute • • Parachute | DIY | School project | sc... • Balloon car • • Balloon Car | DIY | Air powered car |... • Flashlight • • Electric torch or flashlight | DIY | ... • ************************************ • Music • Carefree by Kevin MacLeod is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/...) • Source: http://incompetech.com/music/royalty-... • Artist: http://incompetech.com/
