Cooking with a solar death ray

I love watching cooking shows. Whether the chef is putting a twist on classic comfort food or using molecular gastronomy to expand the palate, it's always good television. But in a TV lineup filled with mystery basket ingredients and auctioned sabotages, is there room for a show that combines DIY science and culinary creations? YouTuber Craig Beals has done just that in his latest video where he demonstrates how to use a solar death ray to grill cheeseburgers. Want to build your own death ray? All you need is the fresnel lens from a projection TV and a sunny day.
