   An inflatable laser maze. This is a non-comprehensive list of inflatable manufactured goods, as no such list could ever completely contain all items that regularly change.An inflatable [1] is an object that can typically be inflated with a gas, including air, hydrogen, helium and nitrogen.

3. Lifting gas - Wikipedia

   en.wikipedia.org/wiki/Lifting_gas

   A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [14] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...

   In 2015 author and right-to-die advocate Derek Humphry reported that Worthington Industries, the world's largest manufacturer of disposable helium cylinders, had announced that their helium cylinders will guarantee only 80% helium, with up to 20% air, making them inappropriate for use with a suicide bag in Humphry's opinion. [23]

5. Balloon - Wikipedia

   en.wikipedia.org/wiki/Balloon

   Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.

6. Helium storage and conservation - Wikipedia

   en.wikipedia.org/wiki/Helium_storage_and...

   Around this time, it was discovered that helium enabled divers to stay under water longer and ascend in a shorter time, presenting another application for helium. In reaction to depleting helium sources, the Helium Act of March 3, 1927 was established to prohibit the sale of helium to foreign countries and for non-governmental domestic use. [8]

7. Helium production in the United States - Wikipedia

   en.wikipedia.org/wiki/Helium_production_in_the...

   The US Army built the first helium extraction plant in 1915 at Petrolia, Texas, where a large natural gas field averaged nearly 1 percent helium. [6] The United States Navy established three experimental helium plants during World War I, to recover enough helium to supply barrage balloons with the non-flammable, lighter-than-air gas. Two of the ...
