Can’t find safe eclipse glasses? Make your own eclipse projector instead.

Buy Solar Glasses at Adorama, 18th Street, between 5th and 6th Avenue.
To watch the solar eclipse on August 21, you could invest in a pair of eclipse glasses. But high demand means high prices—and some of the only reputable retailers are sold out entirely. For a cheaper option, build a pinhole camera, which projects a harmless (but still delightful) image of the sun onto a blank surface.
