On Aug. 21, all of North America will experience a solar eclipse. If skies are clear, eclipse-watchers will be able to see a partial solar eclipse over several hours, and some people – within the narrow path of totality – will see a total solar eclipse for a few moments.

It’s never safe to look at the Sun, and an eclipse is no exception. During a partial eclipse (or on any regular day) you must use special solar filters or an indirect viewing method to watch the Sun. Make sure you’re using proper solar filters (not sunglasses) or an indirect viewing method if you plan to watch the eclipse in person.
You don’t necessarily need fancy equipment to watch one of the sky’s most awesome shows: a solar eclipse. With just a few simple supplies, you can make a pinhole camera that allows you to view the event safely and easily.
