Actually, Bernoulli's Principle has nothing to do with flight. Bernoulli's principle states that low pressure areas and high pressure areas will experience a force towards the low pressure areas. Planes actually fly because the angle of attack and newtons laws of interaction of masseous objects. Cologne/perfume bottles likewise do not match this criterion.
Some good examples:
1) A straw: you suck out the air from within the top portion of the straw, creating a vacuum (low pressure area). the higher pressure outside the area outside the straw forces liquid up the straw and into your mouth until the pressure equalizes
2) a vacuum cleaner: a motor pulls the air out of the vacuum chamber, this creates a low pressure area which pulls up dirt and small particles from your carpet.
3) the upper atmosphere has (some) particles. the higher pressue below pushes particles up to the upper atmosphere and towards the lower pressure vacuum of space. Gravity is what holds the atmosphere from escaping due to bernoulli's principle.

Put a card between a candle and your mouth. Blow on the card. Watch the candle flame move toward you.
Turn on the shower. Watch the shower curtain suck in toward the shower.
A sailboat is propelled partially by "lift" on its sail. It applies to a wing of course (although Bernoulli's principle isn't really what makes it stay up). An eductor/venturi.
