In physics and materials science, a drop tower or drop tube is a structure used to produce a controlled period of weightlessness for an object under study. Air bags, polystyrene pellets, and magnetic or mechanical brakes are sometimes used to arrest the fall of the experimental payload. In other cases, high-speed impact with a substrate at the ...

The driver and passenger front airbag modules, after having been deployed, in a Peugeot 306. An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. [1] It consists of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor.

Frito-Lay employee reveals why bags of chips have so much air in them. A Frito-Lay employee explained why potato chip bags are full of air. TikToker Selena Aragon works in merchandising at Frito-Lay.
Very little attention has been paid to obesity and car crash studies, and it is hard to obtain an obese dummy for the experiment. Instead, human cadavers were used. Body weight is a vital factor when it comes to automobile accidents, and body mass is distributed differently in an obese person versus a non-obese person. [13]
