Periscopes can help you see around corners using two mirrors placed at 45-degree angles. Learn how to make your own with this DIY cardboard periscope video hosted by mechanical engineer Dr. Shini Somara. She talks with Dyson engineers about the ways we can see and use how light travels in straight lines.
The video is one in a series of James Dyson Foundation engineering challenges to get students excited about science and engineering. Download this handy Challenge Cards pdf for the entire set of 44 classic STEM activities, or visit their site for more information.
