The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air, as if blowing up a balloon.
Modellers will use an assortment of balloons, usually in various colors. Balloon sizes are usually identified by a number: the most common size of twisting balloons is called a "260", as it is approximately two inches in diameter and 60 inches long. Thus, a "260" is 2×60 inches and a "160" is 1×60 inches when fully blown up.
The key to understanding the behavior of the balloons is understanding how the pressure inside a balloon varies with the balloon's diameter. The simplest way to do this is to imagine that the balloon is made up of a large number of small rubber patches, and to analyze how the size of a patch is affected by the force acting on it.
It could blow up balloons, smoke, synthesize text, and move his legs and arms. In 1939, he received his pet, and the first mainstream animatronic, Sparko. [11] However, unlike Elektro, Sparko had no built in computer and was not remote controlled, instead using an external computer controlled by an operator. [11]
The inflation valves have caps, which require to be open in order to fill the object with air by placing the lips and blow air inside it manually or use air pump's and closed after finish. To deflate an object and make transport or storage easier, the cap can be opened for the air to be drained and the object can be squeezed so the deflation ...

In mathematics, blowing up or blowup is a type of geometric transformation which replaces a subspace of a given space with the space of all directions pointing out of that subspace. For example, the blowup of a point in a plane replaces the point with the projectivized tangent space at that point.
