One example is the case of the curve ball in baseball. The entire pitching of the ball works because of Bernoulli's principle. Since the stitches of the ball actually form a curve, it is necessary for the pitcher to grip the seams of the baseball. The reason as to why this is a necessity is that by gripping the baseball this way, the pitcher can make the ball spin. This allows for friction to cause a thin layer of air to engi if the misunderstanding of the baseball as it is spinning, but since the ball is spinning in a certain manner, this allows for more air pressure on the top of the ball and less air pressure on the bottom of the ball. Therefore, according to Bernoulli's principle there should be less speed on the top of the ball than there is on the bottom of the ball. What transpires is that the bottom part of the ball accelerates downwards faster than the top part, and this phenomenon allows for the ball to curve downward, which causes the batter to miscalculate the ball's position.

Another example of Bernoulli's principle in our everyday lives is in the case of someone feeling a draft. We all at least one time or another, have experienced feeling a draft, and it is because of Bernoulli's principle that we feel this draft.  Let's say that in your room, you are really hot, but you know that it is nice and cool both outside your window and outside your door. If you open up your window, to try and let fresh air in, there won't be much of a temperature change, unless the door to your room is open to air out the hot air. The reason why it works this way is that if the front door is closed the door will become an area of high pressure built up from the hot air, and right outside the door there is little pressure, meaning that the rate at which the air enters will be in an incredibly high speed. When you open the door, the pressure is relieved from the door on the inside and the hot air exits quickly. When the hot air exits there is a lot more pressure outside meaning that it will take awhile for the cool air to come in. Once the hot air has flown out, the cool air will come in at a fast speed, thus causing a draft.
