Protecting Lives with Explosions

Explosions rarely happen around us.
However, there are explosives around us that can protect our lives in an emergency.
The airbag, which is now standard in every car, is one such example.

The mechanism of an airbag is simple to explain.
When an accident occurs, a bag is filled with air to inflate it and act as a cushion.
That is all there is to it.

However, when an accident happens, there is no time to leisurely inflate a bag.
Even one second is too long. In that time, you could suffer life-threatening injuries.
Therefore, the idea was born to use the gas generated by detonating an explosive.
It was invented by a Japanese person. Yasaburo Kobori conceived it in 1963.

The time it takes for an airbag to inflate is a mere 0.02 to 0.03 seconds. It happens in an instant.
If a person hits a bag that has just inflated, it can be dangerous as they might bounce off it.
Therefore, airbags have holes in them so that they deflate immediately.

At first, airbags were not used because they relied on gunpowder.
However, today almost every car is equipped with airbags.
The car you rode in recently surely contains explosives that protect your life.
