Why Is Helium Used in Balloons?
Helium balloons are a common sight at birthday parties, graduations, weddings and all kinds of celebrations. They’re available in many shapes, sizes and colors. Some are custom-printed for such special occasions as Valentine’s Day or a 50th birthday. Helium is a non-toxic, non-combustible gas that’s lighter than air, so balloons filled with it will float, adding to the party atmosphere. Helium tanks are widely available for rental at party shops, florists and toy stores. Safety Helium is a member of an elemental group called the noble gases, which also includes neon and argon. They don’t react chemically, they don’t burn and they’re non-poisonous. This makes them safe if the balloon should burst or leak. Hydrogen, the other lighter-than-air gas that was used to float balloons, is flammable and may explode if sparked in air. Though the tanks containing helium are under very high pressure, they are all equipped with regulators to make their use safe and simple. Sizes Helium balloons rang
