These have an open hole, and reinflate as they are bounced in play. The balloon is made of glassine paper known as washi, which is air-resistant, glossy and thin, and which has sufficient plasticity to allow it to be formed into a new shape, which it can then retain. [1] The properties of these paper balloon toys are of interest to scientists.
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.
"Self-inflating" cushions have an interior sponge that keeps them in a normally expanded state, and do not require inflation. The cushion is then placed under a seat cushion or other material, for someone unsuspecting to sit on — forcing the air out, causing the flap to vibrate and creating a flatulent sound.
An inflatable laser maze. This is a non-comprehensive list of inflatable manufactured goods, as no such list could ever completely contain all items that regularly change.An inflatable [1] is an object that can typically be inflated with a gas, including air, hydrogen, helium and nitrogen.
It involves using an overall-type harness and a self-inflating balloon with an attached lift line. An MC-130E engages the line with its V-shaped yoke and the person is reeled on board. Red flags on the lift line guide the pilot during daylight recoveries; lights on the lift line are used for night recoveries.
A tube man, also known as a skydancer, air dancer, inflatable man and originally called the Tall Boy, is an inflatable stick figure comprising sections of fabric tubing attached to a fan. As the fan blows air through it, the tubing moves in a dynamic dancing or flailing motion.
