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.

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. [15] 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 ...
A weather balloon, also known as a sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments to the stratosphere to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde.
The enclosed helium atoms escape through small pores in the latex which are larger than the helium atoms. However, some types of balloons are labelled "helium-grade". These balloons are often thicker and have less porosity. [3] Balloons filled with air usually hold their size and shape much longer, sometimes for up to a week.
Elastomeric masks linked to backpack air tanks: self-contained breathing apparatus, worn by firefighters advancing with a firehose. There are two major application areas for SCBA: firefighting, and industrial use in confined spaces. [20] For SCBAs used in firefighting, manufacturers typically prioritize fire resistance and weight reduction over ...
