Airbag: save your life
Airbag: save your life0Driving a car is convenient. But it is sometimes dangerous. When a car hits another car, for example, an airbag inflates to protect the driver. How does the airbag save the driver?
When you blow a balloon, the air from your mouth takes up the space inside the balloon. This means the air has volume. Like this, the air inside the airbag has volume and takes up space between the car and the driver.
Then, where does the air come from? An airbag has a substance that creates nitrogen. If a car gets crushed and gets a spark, it makes the substance active and nitrogen is created. Next, the nitrogen fills the airbag and becomes a buffer.
