While this practice can be dangerous if repeated over and over, since it deprives the body of oxygen, there is no harm in trying it once. Helium tanks, much like propane tanks or fire extinguishers, contain pressurized gas that can explode if handled incorrectly .

Can helium explode with heat?
Explanations: Helium is an “inert” gas and does not react in the presences of heat or air . This is why the balloon filled with helium does nothing more than pop. ... This reaction is highly exothermic, producing the prodigious explosion.
Does helium gas explode?
Helium is not a flammable or explosive gas . Helium is an inert gas, which means that it is very stable and not very reactive. A balloon filled with helium will not explode.
Are helium tanks worth it?
The Verdict. While you need more cash outlay up front, you’ll get more helium for a lower price when you are renting a tank as opposed to buying a disposable one. If you have more than 50 x 9′′ or more than 27 x 12′′ latex balloons to fill, renting a tank is your best choice. It’s also better for the environment.

the valve handle by turning it counter-clockwise. Press and hold down on the tilt-nozzle (see photo 2) until the tank is empty. Listen and feel for pressure discharging from the tilt-nozzle. The tank is empty when no sound is heard or pressure is felt .
Why is there a helium shortage?

What are 3 interesting facts about helium?
Helium has the lowest boiling point of all elements —4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero. Helium is the only element that cannot be solidified by sufficient cooling at normal atmospheric pressure. Helium was the first element not to be discovered on earth.
Why is hydrogen flammable But helium is not?
Helium is an “inert” gas and does not react in the presences of heat or air. This is why the balloon filled with helium does nothing more than pop. Hydrogen gas is very flammable . ... This reaction is highly exothermic, producing the prodigious explosion.
Why is inhaling helium bad for you?
Breathing in pure helium can cause death by asphyxiation in just minutes . Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, blocking it. The blood vessels can rupture and hemorrhage.
What happens if a helium balloon pops?
But, what if they explode and turn into something which you never even expect? A burst of helium balloons can actually harm people in a very bad way . ... This will allow balloons to shrink enough so that the skin will also become thicker and tighter.
Which is lighter hydrogen or helium?
Helium has a molecular weight of 4 and, like hydrogen is lighter than air . While helium is not as light as hydrogen, it is inert and non-flammable (unlike hydrogen, which is highly flammable). For this reason, helium is used to inflate party and meteorological balloons as they will rise in air.
How much does it cost to fill a balloon with helium?
Latex balloons filled with helium typically cost between 50 cents and $1 at party stores. Filled Mylar or foil balloons typically cost $1 to $4 for normal-size balloons, 18-inches in diameter and smaller, or $7 to $15 for oversized or jumbo balloons, which may be 20- to 50-inches in their longest measurement.
Will Dollar Tree fill up my balloons?
