The nation seems to be in the grips of Eclipse Fever, and as the country is gearing up to view this almost once-in-a-lifetime event, we all know that we can’t look directly at the sun, so Pizza Hut has cleverly and simply given us a solution that’ll save our retinas. They’ve released a tutorial video this week which offers up a great secondary use for empty pizza boxes. Their hack is an easy one: You’ll need a pizza box, an 8×11 sheet of white printer paper, a small square of tinfoil, some tape, a pen, and a pair of scissors. It’s kind of like the third grade all over again. The video quickly goes through the steps.
