A Zippo Lighter
Ever wondered how you can light a fire with just the flick of your thumb? Well, this might be able to provide a little bit of insight for all you curious types. Thanks to some quick friction, a fire can appear in your hands in just a moment (or a few, depending on how long it takes you to get a grip on the top of it.)
Toothpaste Tube
When you need to get your mouth clean, you should be grabbing a tube of toothpaste, but make sure it isn't chopped in half like this one is. The pinwheel effect allows for that very cool color combination once you squirt a pea-sized amount onto your brush. Keep those teeth pearly white!
