    1. The area of the edge of a knife’s blade is extremely small. this create a pressure high enough for the blade to cut through a material.
    2. A vacuum cleaner has a fan inside that creates a low pressure inside the device. Consequently, air and dirt particles are sucked into the device.
    3.  The ink dropper that we use almost on a daily basis actually works on the air pressure principle. As soon we create a low pressure by removing the air inside the bulb, the ink flows in to fill in the void.
    4. An aeroplane would take off from the ground based completely on the fact that when we cause the air to move we lessen the air pressure in the immediate surrounding and that helps in lifting the aeroplane.
