Viewers are less than two weeks away from witnessing the total solar eclipse, and the once in a lifetime event is something they will likely want to remember.
The Carnegie Science Center urges viewers to think twice, however, before looking up or snapping a picture.
"That's very dangerous," Mike Hennessy tells FOX. "Because that's focusing light on you that could harm your eyes, and also it can ruin your phone or your camera."
Viewing the eclipse straight on is also a no-go. Hennessy says "it's never okay to look at the sun's rays, even if the moon is blocking part of the sun."
So, here are four ways to safely see the eclipse.
Or, how about a colander?
Hennessy says during a partial solar eclipse, viewers won't actually see those circles.
"What they'll see are crescent shapes on the piece of paper because the moon will be covering most of the sun," Hennessy says.
If it's cloudy, viewers won't be able to see the eclipse at all, but NASA will be streaming the spectacle live on its website.
