One of the inevitable truths of working at an outfit like Popular Science is that companies send you a lot of free, unsolicited stuff in the mail. We’ve amassed an impressive collection of Nerf guns here in the office over the years, and we had a chance to dust them off when a Nerf rep rolled up in an Escalade with two “zombies” inside–just in time for Halloween. We’re happy to report that our brave staff repelled the miniature horde and got back to the business of bringing you all the latest science and technology news.

Happy Halloween!
