Auto-off Candle

Current popularity of lighted candles has led to an increase in property damage and deaths nationwide due to fires started by candles. After noticing candles inadvertently left burning at home, Lisa developed a system of metal bands to control the burn time of candles. A person selects the desired burn time, and the candle will go out automatically when the bands, which cuts off the fuel for the flame, are reached. To reuse the candles just reset the bands and light.
