The “Smart Banana” is the most bizarre use of fruit since you learnt how to make a bong out of a pineapple in Thailand. And, you guessed it, it comes from Japan. To be specific, the Japanese subsidiary of Dole, the biggest fruit and vegetable company in the world, has created what it describes as the “world’s first edible wearable.”

All in the name of a marketing ploy, Dole created the Smart Banana for two runners to use during last week’s Tokyo marathon. Peeled and then filled with an LED display and a smaller banana, the Smart Banana was GPS enabled and displayed the runners stats on the skin. Race times, heart rate and even messages of encouragement were displayed on the fruit.

And of course, the fruit was enjoyed by the runners after the race was over.
