### May 11 **May 11th could be called "The Day of the Wacky Inventions"!** On that day, some of the most incredulous contraptions that the world has ever seen were created - and none more so than these ones: * The Slingshot-Powered Pencil Sharpener. Sure, pencils are supposed to sharpen on their own with a bit of pressure - but why not take it up a notch? This invention did just that by incorporating a little slingshot action to really get those pencils in tip top shape. * The Bouncing Toothbrush. Ever feel too lazy to brush your teeth the traditional way? No problem! Just use this amazing invention and your teeth will be sparkling clean in no time. All you have to do is bounce the toothbrush around in your mouth and it'll do the rest. * The Roll-Up Toilet Paper Dispenser. The closest thing to a magic trick ever invented! This incredible device allowed you to get a steady stream of toilet paper with no effort whatsoever. Just insert the roll and it'll unroll itself at the press of a button. Ah yes, truly a day to remember! There are few things more entertaining or awe-inspiring than the sheer variety of offbeat inventions that continue to fascinate us to this day.
