Transcript of Air has mass

How can I show that air exerts force???
If I hit the packing tape on the open part of the funnel, then the flame will go out. This happens because the air pushes the flame out with its weight.
. plastic funnel
. packing tape
. 15 cm ruler
. one tea light candle
1. Cut off long end of the funnel.
2. Cover large open end of the funnel with packing tape.
3. Measure exactly 15 centimeters.
4. Place lit candle on one end and the funnel on the other.
5. Hit packing tape part of the funnel and watch the effect.
Air has mass :)
When I flicked the packing tape it pushed

flame to go out.
