2. Suction cup - Wikipedia

   en.wikipedia.org/wiki/Suction_cup

   The working face of the suction cup is made of elastic, flexible material and has a curved surface. [3] When the center of the suction cup is pressed against a flat, non-porous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the air or water between the cup and the surface to be expelled past the rim of the circular cup.

3. Backflow prevention device - Wikipedia

   en.wikipedia.org/wiki/Backflow_prevention_device

   For example, when a drinking straw is used to consume a beverage, suction reduces the pressure of fluid inside the straw, causing liquid to move from the cup to inside the straw and then into the drinker's mouth. A significant drop of pressure in a water delivery system creates a similar suction, pulling possibly undesirable material into the ...

   Short hook with a pointed tip is a pike pole; longer hook on a San Francisco hook; two offset hooks on either side of tip is a universal hook; long p-shaped hook is a Boston rake for pulling plaster and lath; short hook with claw on opposite side of tip is either a gypsum hook or the narrower ceiling hook; pike pole with a short handle is a ...

5. Nano-suction technology - Wikipedia

   en.wikipedia.org/wiki/Nano-suction_technology

   Nano-suction is a technology that uses vacuum, negative fluid pressure and millions of nano-sized suction cups to securely adhere any object to a flat non-porous surface. When the nano-suction object is pressed against a flat surface, millions of miniature suction cups create a large vacuum, generating a strong suction force that can hold a ...

   Janet Vivian Hooks [1] [2] (April 23, 1957 – October 9, 2014) was an American actress and comedian. She was best known for her tenure on the NBC sketch comedy series Saturday Night Live , where she was a repertory player from 1986 to 1991.

7. Microsuction tape - Wikipedia

   en.wikipedia.org/wiki/Microsuction_tape

   For micro-suction tape, the necessary force is proportional to the attachment surface area. Compared to a suction cup, the force is smaller for the tape (assuming the same attachment surface area) because only a portion of the surface area contains craters that form vacuum chambers, and the maximal force factor is determined by this portion.
