Ernesto Sevilla and Joaquín Reyes have visited the set of ‘El Hormiguero’ to present their new project, ‘Pobre Diablo’. The couple of actors are inseparable, they have worked together for a long time and have not hesitated to tell their most memorable anecdotes, including the Goya Awards, and that is that both presented the gala in 2019, a gala that many pointed out as ” the worst ever.”
On the occasion of his interview, Marron has brought one of the experiments that have required maximum security on the set of ‘El Hormiguero’. And it is that Marron and his team have blown up a car that was full of airbags and created a surprising effect.
In the Science section we have detonated in a controlled and simultaneous way 30 airbags extracted from junk cars inside a car, and we will see how the enormous mechanical energy they release is capable of destroying the car.
The airbag or airbag is a passive safety system installed in cars that jumps in the event of a collision, (with acceleration greater than 3 G), and its function is to cushion the impact of the occupants against the different elements with the inflatable bags. what is in the vehicle. It is estimated that in the event of a frontal impact, its use can reduce the risk of death by 30%.
This system was patented on October 23, 1971 by the Mercedes-Benz firm, after five years of development and testing of the new system. The first model that incorporated it was the 1981 Mercedes-Benz S-Class W126 and later it was installed in the E-Class W123.
The airbag system in a vehicle is made up of impact detectors, inflation devices by explosive chemical reaction, and nylon bags normally inflated with nitrogen resulting from the chemical reaction.
It takes 30 to 40 msec to inflate at around 300 km/h and it only remains inflated for a few seconds because the gas is expelled through some holes to measure the force applied to the occupant.
It is a complementary system to seat belts. Never substitute.
Inside the bag is a mixture of sodium azide or sodium nitride (NaN3), potassium nitrate (KNO3), and silica (SiO2).
Each device is activated with one or more pyrotechnic devices, commonly called an electrical initiator that consists of an electrical conductor wrapped in a combustible material. The electrical initiator is activated by an electrical impulse, generating high temperature conditions, which cause the sodium nitride to decompose, producing sodium metal and nitrogen gas, which inflates the bag. The sodium metal in turn reacts with the potassium nitrate and silica to generate more nitrogen gas.
