When a vendor selling hydrogen balloons gets into an argument with a passerby
Unexpectedly, the hydrogen balloon suddenly exploded
A large fireball was formed in an instant
Fortunately, no one was injured
In fact
Seemingly beautiful hydrogen balloons
A little careless
will become a floating "bomb"
There are many accidents in which hydrogen balloons explode
Case 1
On February 19, 2023, a girl in Henan Province was playing with a hydrogen balloon when the balloon spontaneously combusted, but fortunately she was not injured, and it was suspected that it was caused by static electricity.
Case 2
On November 29, 2023, a man in Changsha, Hunan Province wanted to pop the hydrogen balloon and throw it away, but when he poked it, the hydrogen balloon exploded directly, and his eyebrows, eyelashes, and hair burned in an instant.
Why do hydrogen balloons explode?
Hydrogen inside a balloon is a low-density, flammable and explosive gas. It is not easy to react with oxygen at room temperature, but it may cause an instantaneous explosion when it is rubbed against other objects to generate static electricity, open flames, sun exposure, or excessive pressure.
Having said so much
So how powerful is the explosion of this popular toy?
Let's see Chuanchuan's experiment revealed
Hydrogen is flammable and explosive

Kawakawa suggests everyone
Whether it's playing on your own

Safety comes first
