Query: Incredible Invention !

Forget about messy cleanup and wasted (expensive) pineapple - this gadget is simple to use and quickly turns that intimidating hulk into a totally cored, ready-to-eat fruit. Use the cored pineapple shell for drinks or fruit displays. I believe the inventor won an international design prize of some kind - he/she deserves it! You will be eating fresh pineapple within 30 seconds, and it cleans in 10 seconds under running water.
