That drawer of half-dead 9-volt batteries in your kitchen just got a little more functional thanks to this simple 9-volt battery flashlight. This flashlight takes the traditional flashlight concept and flips it around. Rather than embedding batteries into the actual flashlight, you embed the flashlight onto the battery. The device consists of three high-powered LEDs and a small on/off switch.

The size of 9-volt batteries makes this flashlight extremely convenient. Throw one in your car, purse and every drawer of the house so you will be prepared when that nuclear fusion project goes horribly wrong and your neighborhood is left without power. These flashlights will be available next month for $10 each. — Travis Hudson
