The good news is, breathing helium does not kill brain cells. The lack of oxygen that comes from breathing in helium can cause fainting or even asphyxiation and death. This is especially likely if you were to breathe several balloons full of helium without getting enough oxygen in between. Regarding this, is it dangerous to inhale helium?
According to the NIPC, huffing helium can cut off oxygen supply or can cause an embolism if a person inhales too deeply. In addition, pressurized tank gas can cause lungs to rupture. Dangerous inhalants now include helium, NIDA says.
Also Know, what does helium do to your voice? Helium is lighter than air. Which means sound moves faster through helium than through air – nearly 3 times faster, in fact. So the sound waves bounce around faster in your vocal tract, which amplifies the higher frequencies in your voice. It's sort of like how speeding up your voice makes it sound higher.
Moreover, is it OK to inhale helium from a balloon?
You inhale helium from a balloon, and almost as if by magic, you sound like a cartoon chipmunk. Harmless as it may seem, though, inhaling helium can be dangerous — deadly, in fact. There are numerous case reports of serious injury and even death caused by helium inhalation.
Can helium permanently change your voice?
No, the helium only change the composition of air in your throat and cause the soundwaves from your vocal cords be transmitted differently, but it does not change the way your vocal cords works. As soon as you breath out the helium, your voice return to normal.

Is helium bad pregnancy?
A:Helium exposure is not harmful to mothers or the fetus unless there is an explosion. Helium is sometimes used in the treatment of acute asthma because it is inert. Can you smoke helium?
Let's get this out of the way first: Do not ever inhale helium. We know, no one has ever told you this, but inhaling helium can kill you or cause serious injuries and it's used to commit suicide all of the time. So don't do it. Is helium an explosive?
Helium is a special gas called a Noble Gas, which means it doesn't burn. When a match is held near a helium-filled balloon, the balloon pops. But when a match is held near a hydrogen-filled balloon: BOOM! a real explosion. How can I make my voice sound like helium?
You can breathe in helium to change the sound of your voice and illustrate how density affects the speed of sound. You can pick up a helium-filled balloon at many grocery or party supply stores. To make your voice squeaky, you just exhale air, take a deep breath of helium and talk (or sing, if you're extroverted.) Does hydrogen make your voice higher?
The molecular weight of hydrogen is half of helium. So the speed of sound is higher and that will increase the acoustic resonant frequency of volumes filled with hydrogen (such as your throat and mouth). Could a balloon float into space?
A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The air in Earth's atmosphere gets thinner the higher up you go. So, this is as far as a helium balloon can rise. Outer space starts somewhere around 600 miles (960 kilometers) above Earth's surface. What air makes your voice deeper?
This is the inert gas that is six times heavier than the air we breath. If you breath in helium (six times lighter than the air we breath), the pitch of your voice goes up. However, if you breath sulfur hexafluoride (six time heavier than normal air), your voice sounds low. Why does sound travel faster in helium?
The speed of sound in helium is faster than in air because the helium is lighter than air. Sulfur hexafluoride makes your voice sound very low because sound travels slower in heavy gases. Who discovered the helium?
Pierre Janssen Per Teodor Cleve Norman Lockyer How do you make helium?
There is no chemical way of manufacturing helium, and the supplies we have originated in the very slow radioactive alpha decay that occurs in rocks. It costs around 10,000 times more to extract helium from air than it does from rocks and natural gas reserves. Helium is the second-lightest element in the Universe. What is the state of helium at room temperature?

Why does helium make balloons float?
The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air.
