pinhole

People without protection can still view the eclipse indirectly through a homemade pinhole projector.

With your back to the sun, position the foil side of the box over your shoulder, letting light stream through the pinhole.

You can also indirectly see the eclipse by using a pinhole projection.

“The sun will be a little bit brighter, but you shouldn’t ever look at it except during totality without either approved eclipse glasses or in the correct pinhole camera,” Christian said.

If you don’t have eclipse glasses, you can use an indirect viewing method such as a colander or pinhole projector.
