Can't find eclipse glasses? Here's how you can watch the eclipse without them

Eclipse glasses are sold out just about everywhere. But if you didn't get a pair, you can still watch Monday's solar eclipse.

It's free - and pretty easy - to find or even make a device that will help you see a projection of the eclipse.

Option 1: Cardboard box pinhole projector

You can make a viewer with a small cardboard box, a thumbtack and some aluminum foil. Google "shoebox solar eclipse viewer" and you'll find YouTube videos and detailed instructions for making a pinhole projector.

Fruity Pebbles wants you to make your pinhole projector from - surprise - a cereal box. Here are the cereal maker's NASA-approved instructions:

1) Empty the box of cereal and feel free to munch on the Fruity Pebbles while you begin DIYing.

2) Cut out a rectangle shape of white paper or cardboard that will fit snugly inside the bottom of the box and tape into place.

3) Cut a square shape on the left and right sides of the top of the box and tape up the center.

4) Cover one of the square holes with aluminum foil and tape into place.

5) Using a small nail or pencil, poke a small hole in the foil.

6) When the eclipse comes, look through the open square, with your back facing the sun. A reflection of the sun will be projected through the foil and onto the white paper inside the box Remember, never look directly at the sun!

Option 2: If you don't want to do a craft project, just look for something that casts a shadow on the ground. Anything with small holes will do - a colander, for instance, or even an index card with a hole in it. Stand with your back to the sun, hold up your hole-filled object and watch the shadow it casts on the driveway or sidewalk. In the light that shines through the hole, you'll be able to see the crescent of sunlight change as the moon moves across.

No matter what you use, remember this: You shouldn't look directly at the sun without protective glasses. And regular sunglasses don't count.
