Science: Hydrogen is extremely inflammable, and it leaks in small volumes from balloons. A lift has static electricity as well as electronic components. Even a tiny spark can result in an explosion. So why do people buy them? Mostly, they don’t. They are victims of a scam. They think they are buying helium balloons, but vendors instead give hydrogen ones because hydrogen is much cheaper. Lesson: Buy helium balloons only from reputable vendors. | The Skin Doctor
