|The third blessing is recited over the special, multi-wicked Havdalah candle. Havdalah candles can be obtained from Jewish gift stores. If you cannot obtain a Havdalah candle, you can hold two candles close together, so their flames overlap. I have also used party candles (long, very thin candles) that I warmed up and twisted together.
Lighting a flame is a vivid way of marking the distinction between the sabbath and the weekday, because we cannot kindle a flame on the sabbath.
After the blessing is recited, hold your hands up to the flame with curved fingers, so you can see the shadow of your fingers on your palms. This is done because it would be improper to recite a blessing for something and then not use the thing.
