The cost is much higher than that of hydrogen balloons! Now the wedding market does not use hydrogen balloons, which is cheap, but hydrogen is flammable and explosive! A few years ago, people all over the country were injured by the explosion of wedding hydrogen balloons, and later they switched to helium. Everything is safety first!

Hydrogen is not only used in the wedding market, but also in floating gas columns, balloons and colored balls for general celebrations. Hydrogen has been banned in the civilian market!

Therefore, I would also like to remind you that few people buy hydrogen balloons for children to play with in some local squares. If they accidentally explode and burn, the consequences will be very serious!
