Smart UV sensor stickers that tell you when to reapply sunscreen—via a gentle wasabi tingle
Meet ReefRanger: a clownfish-shaped smart sticker that adheres to your sunscreen bottle or skin. When UV protection fades, it releases a micro-encapsulated wasabi essence creating a mild tingling sensation. Made from recycled fishing nets, returnable to build artificial coral reefs.
GET YOUR REEFRANGERYou're swimming in the ocean, distracted and having fun, when suddenly your shoulder starts tingling with a warm, spicy wasabi sensation. You look down and see your clownfish sticker glowing orange. You realize your sunscreen is wearing off at the perfect moment—before any damage occurs. Later, you mail back the used device and get a GPS coordinate showing exactly which reef structure your returned device helped build.
