'MURICA — If you've spent anytime on Twitter lately, you've probably noticed the latest internet challenge. <br /> <br />It's called the Invisible Box Challenge. It involves an invisible box, too much time on your hands and something to film yourself with. <br /> <br />First take your invisible box and then put in on the ground. Be careful where you put it, because it could be a tripping hazard. <br />Next find your imagination. If you don't have your own, borrow someone else's. <br /> <br />Then, place one foot on the invisible box and step over it. Easy as pie. Okay, maybe it's not that easy. <br />Hey, it beats dumping a bucket of ice over your head, and it's eco-friendly.
