Children blow soap bubbles and play in the spray of a sprinkler on a hot summer day. See [link]. An underwater spider keeps his air supply in a shiny bubble he carries wrapped around him. A technician draws blood into a small-diameter tube just by touching it to a drop on a pricked finger.
Climate loads in insulating glass units: comparison of theory and experimental results
How Does a Suction Cup Work? | Sciencing
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure , or air pressure. It is the force exert ed on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.

A suction cup is what you use when you want to hang a poster on a glass window or pick up a sheet of glass. They are perfect for attaching to any flat, non-porous surface and will adhere with a lot of force if applied correctly. They are made from soft rubber and stick to a surface using the force of air pressure. The suction cup must meet three criteria to work properly: It needs to have a "cup" shape with concave center and flat spreading sides, it must adhere to a flat, non-porous surface, and be made of air-tight material.
Please take this quick survey to tell us about what happens after you publish a paper. The verification of insulating glass units in ultimate limit state often gives rise to the question of how to take into account the edge seal in the design of the glass panes. Usually the edge seal is calculated as immovable, as this is a more conservative assumption. A flexible edge seal, as to be expected under realistic conditions, leads to a lower climate load and therefore to lower stresses in the glass.
