A new sticker for fruit turns into 'fruit wash' when it's put under water and rubbed with a finger. Soon you may be able to clean the gunk off your fruit with . . . the other gunk on your fruit.
Labels on fruit suck. For one thing, it sucks when people put labels on anything, man, it's like officially limiting what they can do, and that's wrong. They give little or no information to the consumer (I don't still need to be reminded that it's good to eat fruit, banana companies). And they present a practical challenge. It takes time and fingernails to pull them off, often you puncture the fruit in the attempt, and they leave behind nasty little whitish-brown sticker-guano behind. (And this is separate from those people - who shall remain nameless but hated - who peel the stickers off the fruit and stick them on furniture all over the house so you're finding them eight months later.)
But a new fruit label has been developed that stops all of that, and cleans your fruit. Vanishing Fruitwash Labels, developed by Amron, are printable stick-on labels that, when rubbed, turn into soap. The soap takes away dirt and pesticides left on the fruit (and hopefully any sticker-guano as well). The label, it seems, is water-resistant, so it might take some elbow grease to get it off. The company is eager to point out that it can be peeled off as well, but where's the fun and hygiene in that?
Clearly the next step, in my mind, is to adapt this technology into clothing form. I'd really like some clothes that, when rubbed and put under warm water, dissolve into soap that washes me down as I shower. Anyone getting on that?
