Unfortunately, we’re going to be in an airplane during the highly anticipated total solar eclipse in August, so it’s questionable as to what we’ll be able to see of it. But, if you’re going to be on the ground, mark your calendar because this is not to be missed. The only issue: you’ll want to have glasses to protect your eyeballs, even if you’re in the areas where you’ll only see a partial solar eclipse.

But, lucky you! There are a bunch of libraries (like 4800 or so) across the country that are giving them away for free. They’ve got around 2 million pairs to give away, so if you’re a space geek like me (and my family), you’ll want to check to see if your local library (or one near you) has some. Then keep them in a safe place for when this total solar eclipse hits on August 21, 2017.
