Item Details

  • One of the major properties of Helium is that it's much lighter than air. Consequently, the entertainment industry frequently uses Heium to fill balloons. Take not that inhaling Helium can be deadly; it can cause anoxia. Oxygen is needed to maintain life. If another gas is ihhaled, such as Helium, it displaces the much-needed Oxygen and can cause death.
