Easy DIY: Pinhole Camera
If for some reason you haven’t heard, there’s an eclipse happening tomorrow. It may be too late to get eclipse glasses but you can still safely see the eclipse with a pinhole camera. It’s super simple and you can make it with things you already have at home–card stock, tape, and tin foil. Just cut a square, tape some foil and poke a hole. The full instructions are on the NASA website.
