— -- If your approved solar eclipse glasses didn't come in time or stores near you are sold out, it's not too late to safely see the eclipse. Using items you can find around the house, you can make a pinhole projector, which allows you to see a reflected image of the event.

While eclipse glasses filter out light, the pinhole camera projects the light from the sun onto another surface, so you're looking at a reflected image instead of directly at the sun.

Sara G. Miller of Space.com shared her easy tips for making a pinhole projector at home with "Good Morning America."

"This is a fun, simple science project that you can do at home, so there's no reason that you should miss out on the Great American Solar Eclipse today," Miller said.

How to use it

Take your pinhole projector outside and face away from the sun so that its light shines into the pinhole.

Look through the hole you did not cover, and you will see the sun projected on the paper inside the box.
