 Hi, I'm Zoe Slackin at Aeronautical and Astronautical Engineering major at Purdue University, and the past president of the Purdue Space Program. I'll be answering one of the most searched for questions about this year's total solar eclipse. If you're as excited as I am about seeing this eclipse, you've probably wondered how you're going to protect your eyes from the sun while the eclipse is happening. We all know the sun is dangerous to look at directly, even when partially covered by the moon. The best way to watch the eclipse is by using solar viewing glasses or handheld solar viewing device, like this. The best kind of eye protection is available from a lot of major retailers online. You can even use special filters for telescopes and binoculars that are designed specifically for solar viewing. What makes these safe to use during an eclipse is a special material that is thousands of times darker than your favorite pair of shades. You can also try this cool trick for watching the eclipse without looking at the sun at all. Simply take a piece of cardboard or an index card, poke a hole through it with a pencil, stand with your back to the sun, and watch the eclipse unfold by looking at the shadow cast by the card. You'll be able to see the shadow of the moon pass in front of the sun without putting your eyes at risk. You can also use any household item with small holes in it for the same effect, like a colander. However, you decide to watch the eclipse, albeit the Indianapolis Motor Speedway, alongside Purdue and NASA experts. Get your tickets to join us at purdue.university forward slash solar dash eclipse.
