Human ancestors rubbed two twigs to make fire for cooking and light. Designer for Simple Artiface, Michael Kritzer, got inspiration from which and created a design named Lightstarter for your swanky and classy camping trip. It has an accelerometer embedded which determines how long of the emitting light depends on the time that user rub it in hands. The ratio of the kindling time for Lightstarter is 1:10, which means 1 second of kindling is equal to 10 seconds of light and 30 seconds kindling can give you 5 minutes of light.
