Enter the stage holding a LIT white candle in one hand and a red hanky in other hand.
You cover the candle with the hanky.
The flame of the candle is seen above the hanky.
Suddenly he uncovers the candle. The candle has changed its color from White to Red!
The performer takes another hanky, blows out the candle and covers the candle with the hanky.
The hanky falls and the candle has totally vanished!
