Candle flame

Experiment from Ania&Jessika

Necessary components:
candle, funnel, matches
Description of the method of execution:
Light a candle. Blowing vigorously through the funnel next to a candle flame. Flame leans toward the blast.
Blowing next to a candle flame produces a stream of air. The air pressure outside the stream is greater than in its interior. The difference in pressure causes the outer layers of air movement toward the interior of the stream. Candle flame bends as indicating the direction of the resultant air movement.
