The Fresh Flashlight Maker
It may not cure bad breath, but it will light up your night anyways. This kit includes everything you need to play MacGyver and make your own flashlight from an Altoids tin. All you need is a soldering iron, electrical tape, and a cutting tool to get started.
Step-by-step instructions are included along with a tin, 3V coin cell battery, push-button switch, blue LED, resistor, and hookup wire. You'll have the coolest flashlight in your crew...or at least the mintiest!
