Here is a lists of Bernoulli Principle Demonstrations/where you encounter this principle in daily life or use it to save your life.
1.  Picking up pennies on a table:  Set a penny (or two or more) on the edge of a table and place your mouth off the table so you can blow a short fast pulse of air parallel to the top of the penny.  The penny will lift onto your hand or into a tilted cup on the far side of the penny.
2.  Ping pong ball:  Blow air through a straw vertically suspending a ping pong ball in the air.  The use of a hair dryer (maybe with the upper half of a cut in half plastic water/soda bottle on the end of the hair dryer in order to increase the velocity of the air out the smaller hole of the bottle) can magically keep the ping pong ball a float at a 45 degree angle or more.  Can also blow air through an inverted funnel with the ping pong ball in the funnel.  One would expect the ball to fall out of the funnel to the floor but the air flowing through the small end of the funnel supports the ball.
3.  Same as #2 only a leaf blower/shop vac with larger light ball (beach ball/kick ball).
4.  Hold an 8.5" x 11" piece of paper by both hands up to your mouth so the other end of the paper curves down.  Then blow air across the top of the paper and the lower part will rise so the paper is flat parallel to the floor.  Or simply just blow between two sheets of paper hanging down parallel to each other and they will come together.
5.  Same as #4 only place a half roll of toilet paper on a dowel stick and use a leaf blower/shop vac to blow air across the top of the roll so it all unravels onto the floor.  Maybe cause the roll to unravel high up at an angle for more of an effect.
6.  Two balloons hanging from the ceiling by thread/string so they are 2 or 3 inches apart and blow air between them.  (blowing the air through straws may be helpful)
7.  Two empty soda cans laying on their side a few inches or less apart and blow air between them and they will be drawn into each other.
8.  Next time you run water in your kitchen faucet, notice the stream gets narrower at the bottom due to the acceleration of the water as it falls.  The faster the liquid goes the narrow the stream due to lowering the pressure compared to the normal air pressure in the room.
9.  If your shower curtain attacks you while in the shower it is due to the falling water causing a low pressure in the tub area.   Place magnets so they attract each other at the base of the shower curtain for weight to make it harder to move.
10.  If you are standing next to a track/road and are expecting a train/car/subway to fly by you, STAND BACK, as it will draw you into it from the low pressure.
11.  Two ships/two trains/two semi's/two cars cannot pass each other at high speeds without being drawn into each other and crashing.  That is why you see a train/ship wait for the other to pass before proceeding itself.  If you pass a semi on the interstate do not stay close to it as it causes a tunnel of air that sucks you together.
12.  The curve ball in baseball is caused by the Bernoulli's Principle (B.P.)
13.  A sail boat is allowed to sail against the wind due to the B.P.
14.  Talking about B.P.?  When one puts gas in the car, the pump will automatically shut off due to the Bernoulli Principle actually.  This video calls it something else but it is B.P.
15.  If you teacher walks down the hall with a basket of papers to fast the top paper will lift up and fly onto the floor.  When this happens to me, I say, that darn Bernoulli Principle.
16.  When a roof is taken off a roof the weather people are careful not to call it a tornado because like in #15 it only takes a gust of wind to lift a roof off a house.  (Note:  My wife and I were visiting my brother when a gust of wind took off his neighbor's roof.
17.  If you build a dock for docking boats use pilings (post) instead of a solid concrete/steel dock as the water flowing between the docked boat and the wall with cause the boat to be drawn into the wall.
18.  Of course birds, airplanes, flying debris in a tornado, wind across the top of your umbrella braking your umbrella are all common B.P. phenomena.
19.  Perfume bottle atomizer, the draft in a chimney (any draft actually), a Hoover bugle (a long corrugated tube swung over your head) will suck air like a vacuum cleaner.


Hopefully these demos/B.P. everyday phenomena gave you a little lift to your day!

Below are videos that even show how knowing the B.P. can make you a much faster swimmer.

Bernoulli's Principle:  Faster the fluid (water, air, oil, etc.) the lower the pressure.

Note:  Objects move from a higher pressure toward a lower pressure.
