How powerful are firecrackers?
Actually, if you really want to talk about power, it doesn’t have much power. Firecrackers are nothing more than filled with a little ignition powder. When ignited, they will make a bang and make a little sound, that’s all. The power really isn’t that great. But some things like skyrocketing cannons will indeed have a certain power.
Will the firecrackers falling under the car and exploding damage the car?
Generally speaking, not. As long as it is a car that is regularly maintained and there is not much oil leakage on the chassis or exposed wiring harnesses, the firecrackers exploding at the bottom of the car will not have any impact on your car. At most, it may scare away hiding under the car. Resting cats and dogs. Generally speaking, there is basically no need to worry about cars that are not very old. What we need to worry about is those older cars.
For a car that has been used for many years, the chassis may have leaks that you usually do not notice, such as transmission oil, oil or even fuel, These are all likely to cause some leakage through the aging components. In the extremely low probability, the firecrackers will ignite these combustible fuels and cause combustion, but believe me, if a firecracker can ignite, the oil leakage of the chassis will be early. It’s serious enough that you have to take your car to the repair shop.
The real threat is the electronic circuit. In some older cars, the chassis wiring harness will sag, and the snakeskin protective layer on the outer layer of the wiring harness will fall off due to aging, exposing the wiring. And these lines may also cause the rubber layer of the wiring harness to age and harden due to the harsh environment under the vehicle. At this time, although the power of firecrackers is small, some larger firecrackers will still break several wires, which you cannot see in routine inspection.
