Helium, the ultra-light gas found in airships and birthday balloons, has a quirk that makes it invaluable for science and medicine. With a freezing point of -458°F (-272.2°C), it is only a liquid at all but the coldest of temperatures, making it an ideal substance for supercooling the electronics and magnets that run biomedical equipment.

How To Make A Balloon Float Without Helium
Because Helium is lighter than air, but it is not the only gas we can fill the balloon, we may use hydrogen gas as well. The density of hydrogen gas is 1/2th of the mass of helium gas so we can consider it to make a floating balloon. Air can also be used to fill the balloon. Here we will use a different concept.
Could airplanes be equipped with a flotation device filled ...
Answer: There's already something somewhat similar, but it doesn't use helium. Helium is just an impractical way to go about it. Buoyancy works by displacing a fluid, with the buoyant force being equal to the weight of the fluid you've displaced. Well, air doesn't weigh very much, so you have to ...

Helium is one of the basic chemical elements. In its natural state, helium is a colorless gas known for its low density and low chemical reactivity. It is probably best known as a non-flammable substitute for hydrogen to provide the lift in blimps and balloons. Because it is chemically inert, it is also used as a gas shield in robotic arc ...
14.4 Archimedes' Principle and Buoyancy | University ...
In equation form, Archimedes' principle is. F B =wfl, F B = w fl, where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object. This principle is named after the Greek mathematician and inventor Archimedes (ca. 287–212 BCE), who stated this principle long before concepts of force were well established.
