On April 8, several U.S. states will be plunged into total darkness as a solar eclipse makes its way across the country.Around 31.6 million people across over 12 states—Texas, Oklahoma, Arkansas, Missouri, Illinois, Indiana, Ohio, New York, Pennsylvania, Vermont, New Hampshire and Maine—will be in the path of the totality, with millions more able to view a partial eclipse. This will mark the last total solar eclipse visible from the contiguous U.S. until 2044.
How to make a pinhole cameraYou can create a simple pinhole projector to indirectly view the eclipse. Instead of staring up at the sun, you'll see the eclipse projected onto a screen surface.An easy pinhole camera can be made using two pieces of stiff cardboard, some aluminum foil, tape, scissors, and a pin or needle.First, take one piece of cardboard and cut out a small square or rectangle from the center. This will be the frame of your pinhole projector.
