Question

How long does an airbag stay inflated for? They always deflate very quickly.
Nick, Watford

Answer

** Definitive **
Name: Aaron, Bermondsey
Qualification: 27 years as a mechanic
Answer: They inflate for between 0.2 and 0.5 seconds, then as soon as your head hits the bag, it deflates to slow down the acceleration of your head, rather than bouncing off the balloon.
