Danger

The danger of the nozzle

Filling balloons with helium seems harmless, but it certainly isn't. At the end of 2023, when I was filling the first balloon, the black nozzle that comes with the tank exploded. The pressure wave that was released was so high that even the veins in one of my eyes had burst. My hearing has been damaged, resulting in tinnitus. I strongly advise you to wear hearing protection and safety glasses if you still want to use such a tank. Under no circumstances should children be allowed near a Heliumtank when you are using it.
