How to make your own solar eclipse viewers

How to make your own solar eclipse viewers

You don't need fancy glasses or equipment to watch one of the sky's most awesome shows: a solar eclipse.

Eye doctors warn even looking at the sun for a short period of time can cause permanent blindness.

This is especially great for kids to use since they won't ever have to look at the sun and risk hurting their eyes.

And that's it. You've built your own pinhole projector so you can safely watch the eclipse.

Tape aluminum foil over one of the openings and then use a nail or the head of a pen to push a hole through the center of the foil.

Tape the piece of paper inside the bottom of the box and seal the cereal box up. Just prick a pinhole onto the center, turn your back from the sun, and find a clear enough surface to project the eclipse onto.

NASA's Jet Propulsion Laboratory at the California Institute of Technology has also released tips on how to make a pinhole camera with two pieces of white card stock, aluminum foil, tape and a pin or a paper clip. On the open rectangle at the top of the box, you will be able to peer inside and see the sun's reflection from the tiny pinhole.

Tape the sheet of paper on the inside of the other end of the box.

First, trace a piece of paper that will fit along the bottom of the cereal box and cut it. Stand with the sun behind you, and the magic will happen. When viewing the eclipse, hold your viewer in front of you with the sun shining through the hole. What you'll see inside the box should be an inverted image of the eclipse-called the camera obscura effect.
