{"product_id":"periscope-how-things-work","title":"Periscope - How Things Work","description":"\u003cp\u003eA periscope is a useful example of the law of reflection at work. It's important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. This sends light directly down the tube and onto the lower mirror. This mirror, also at a 45° angle, reflects light directly to your eye.\u003c\/p\u003e\n","brand":"Paul Lamond Games","offers":[{"title":"Default Title","offer_id":54308722606417,"sku":"ZPL-L08703","price":7.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/9097\/1729\/files\/Periscope-How-Things-Work.jpg?v=1783946534","url":"https:\/\/www.toystreet.co.uk\/products\/periscope-how-things-work","provider":"Toy Street","version":"1.0","type":"link"}
