Candle Light responds to the temperature of the air when people breathe out. The idea was developed from both the human behaviour to blow out the candle light and to make vague the windows by exhalation for fun. developed such characteristics into the motif of interactive design. A simple action, blowing out, connects to the function, the brightness of the light. The product is consisted of a LED light and a temperature sensor. The higher the temperature you blow out, the blighter the light becomes. Also as he or she blows more often, the light spreads wider. It lasts for few hours and gradually dims down as time goes by.
