2. Bernoulli ’ s Theorem When air flows fast the pressure of the air is lowered

3. Bernoulli ’ s Theorem When air flows fast objects move towards the fast flowing air

4. Normal air pressure Normal air pressure Normal air pressure

5. Still air Normal pressure Fast air Low pressure Blow Still air Normal pressure

6. Blow Fast air Low pressure Still air Normal pressure
