  • $45.00 replacement fee on a regulator returned damaged.
  • Ribbon or any other means to tie down balloons not included.
  • 11″ helium inflated latex balloons will float indoors 10 to 20 hours and will gradually start to descend. Consequently, they will float less than half this time outdoors.

  • Helium inflated foil balloons will last 5 to 7 days while under the right conditions, several months.
  • Allow at least 24 hours notice for pick-up or delivery.

Now for some fun helium facts!

Besides making our voices sound funny, what is there to know about helium?  Quite a bit, actually!


  • The 2nd most abundant element in the universe.
  • Available on the open market for the first time in 1928.
  • Is so light that Earth’s gravity cannot hold on to it. Consequently, when helium atoms released into the atmosphere rise until they escape into space.
  • Helium exists in the Earth’s atmosphere constantly resupplied from two sources; Decay of radioactive elements on Earth and cosmic ray. About 9% are high energy helium nuclei.
  • The helium sold in cylinders is produced by the natural decay of radioactive elements in the earth’s crust, principally thorium and uranium.
  • Current world production of helium is over 30 000 metric tons a year. Helium has been accumulating for many millions of years in a few natural gas fields. Therefore, we can currently extract more each year than uranium and thorium decay create.
  • Is not flammable, very safe to use.
  • Most noteworthy, helium can be fatal when inhaled as it displaces the oxygen in your lungs. Although it’s fun to speak after inhaling helium, don’t do it!
