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. Self-sealing suction cup - Wikipedia

   en.wikipedia.org/wiki/Self-sealing_suction_cup

   The self-sealing suction cup is a suction cup that exerts a suction force only when it is in physical contact with an object. Unlike most other suction cups, it does not exert any suction force when it is not in contact with an object. [1] Its grasping ability is achieved entirely through passive means without the use of sensors, valves, or ...

4. 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 ...

5. 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.

6. Laboratory glassware - Wikipedia

   en.wikipedia.org/wiki/Laboratory_glassware

   Scientific glass blowing, which is practiced in some larger laboratories, is a specialized field of glassblowing. Scientific glassblowing involves precisely controlling the shape and dimension of glass, repairing expensive or difficult-to-replace glassware, and fusing together various glass parts.

7. May 1981 - Wikipedia

   Police unsuccessfully tried to stop him by lowering a window-washing scaffold, but Goodwin moved sideways with the aid of suction cups along the glass facade. At the 55th floor, Goodwin and the police negotiated a deal, allowing him to climb to the roof of the 110 story tower, and then to be arrested. [58]
