  Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (9 Favorites)

  The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

  Video: Ingenious Video 3: This Sandwich Will Save Your Life in an Arc Flash Mark as Favorite (3 Favorites)

  It’s never fun when your clothes catch on fire. And while “stop, drop, and roll” may be a good idea sometimes, in more extreme cases, you need a better plan. Every day, industrial workers, firefighters, and soldiers risk fiery situations that might seem hard to imagine. In an arc flash event, for one, temperatures can jump to metal-melting levels in milliseconds. How can anyone possibly survive that? Well, take a tip from a club sandwich, because it’s all about the layers. The composite fabrics that protect life and limb in these situations rely on some incredible, multilayered chemistry, including the ability to quickly form a protective carbonaceous crust around the wearer.
