You've probably seen those DIY science videos or "life hacks" claiming you can whip up a batch of balloon gas in your kitchen using some aluminum foil and drain cleaner. It’s a lie. Honestly, it’s not just a little bit wrong; it’s scientifically impossible. What those videos are actually showing you is the production of hydrogen gas. While hydrogen makes balloons float, it also has this nasty habit of exploding if a birthday candle gets too close. If you want to know how to make helium, the reality is far more grounded in geology and deep-time physics than in a chemistry set.
Helium is the second most abundant element in the universe, but on Earth, it’s surprisingly rare. We can't just "make" it in a factory. We have to mine it. It’s a byproduct of billions of years of radioactive decay happening deep beneath the Earth's crust. Think about that for a second. Every time you suck down a lungful of gas to make your voice sound like a chipmunk, you’re using a resource that took an eon to form.
The Physics of Why You Can’t Just Build Helium
Let's get technical for a minute. To "make" helium from scratch, you’d need a nuclear fusion reactor. Stars like our sun do this every day. They smash hydrogen atoms together under unfathomable pressure and heat to create helium.
In a lab? We’re still decades away from making nuclear fusion a viable, net-positive energy source, let alone a cost-effective way to fill party balloons. You can't just rearrange molecules to get helium because helium is an element, not a compound. It’s an "unreactive" noble gas. It doesn't like to bond with anything. This makes it incredibly useful for cooling down superconducting magnets in MRI machines, but it also means you can't synthesize it through a simple chemical reaction.
The Alpha Decay Secret
So, if we aren't getting it from the sun, where does the stuff in the tank come from? It’s basically "alpha particles" that have settled down and found some electrons. Deep in the Earth, heavy elements like uranium and thorium are unstable. As they decay over millions of years, they spit out alpha particles.
An alpha particle is basically a helium nucleus—two protons and two neutrons. Once that particle slows down and grabs two electrons from its surroundings, it becomes a stable helium atom. This happens in the dark, hot depths of the crust. The gas then slowly seeps upward until it gets trapped under impermeable rock layers, usually alongside natural gas deposits. That is the only way "new" helium appears on our planet.
How We Actually Extract Helium (The Industrial Reality)
Since we can't manufacture it, we harvest it. This is a massive industrial undertaking. Most of the world's helium comes from natural gas fields, specifically those in the United States (like the Hugoton Field in Kansas, Oklahoma, and Texas), Qatar, and Russia.
But you can't just poke a straw into the ground. The natural gas coming out of a well might only contain 0.5% to 4% helium. To get the pure stuff, engineers use a process called cryogenic distillation.

- They take the raw natural gas and strip away impurities like water, carbon dioxide, and hydrogen sulfide.
- The gas is then cooled to extremely low temperatures. Because different gases liquefy at different temperatures, they can separate them.
- Methane—the stuff you burn on your stove—liquefies at around -161°C.
- Helium is the ultimate holdout. It doesn't turn into a liquid until it hits -268.9°C, which is just a few degrees above absolute zero.
By the time everything else has turned into a liquid, the helium is still a gas. This "crude helium" is then further refined to 99.999% purity. It’s a grueling, energy-intensive process. It’s why helium prices spike whenever a major plant goes offline for maintenance.
The Helium Shortage: Are We Running Out?
You might have heard headlines about a "global helium shortage." It sounds like a joke—how can we run out of an element? But the concern is real. Because helium is so light, once it escapes into the atmosphere, it doesn't just hang around. It literally floats off into space. It’s gone forever.
For a long time, the U.S. Federal Helium Reserve in Amarillo, Texas, kept prices artificially low by selling off a massive stockpile created during the Cold War. But that stockpile is dwindling. We’ve moved into an era where we have to rely on private production.
Dr. Chris Ballentine from the University of Oxford has been a leading voice in finding new ways to locate helium. In 2016, his team helped discover a massive helium field in Tanzania's East African Rift Valley. They found that volcanic heat "kicks" the helium out of ancient crustal rocks, allowing it to collect in shallower reservoirs. This was a game-changer because it proved we can find helium independently of fossil fuel exploration.
Why We Need Helium (It's Not Just for Balloons)
If it were just about party decorations, nobody would care about the supply. But helium is a "critical mineral" for modern life.
- MRI Machines: The most vital use. The superconducting magnets in MRIs need to be bathed in liquid helium to stay cold enough to function. No helium, no high-res brain scans.
- Semiconductors: Making the chips in your phone requires an ultra-clean, inert environment. Helium is perfect for this.
- Space Exploration: NASA uses massive amounts of helium to purge rocket engines and pressurize fuel tanks.
- Deep Sea Diving: Divers use "heliox"—a mix of helium and oxygen—to avoid nitrogen narcosis and the bends at extreme depths.
Misconceptions About Making Helium at Home
Let's address the elephant in the room: the "vinegar and baking soda" or "caustic soda and aluminum" myths.
When you mix sodium hydroxide (drain cleaner) with aluminum foil, a vigorous reaction occurs that releases gas. That gas is hydrogen. It is highly flammable. In the 1930s, the Hindenburg was filled with hydrogen. We all know how that ended. Using hydrogen for balloons at home is a recipe for a house fire.

The other common myth involves "extracting" helium from the air. While there is helium in the atmosphere (about 5 parts per million), it is so incredibly diluted that trying to suck it out would be like trying to find a specific grain of sand on a beach. It’s theoretically possible but economically insane. It would cost thousands of times more than mining it from the ground.
The Future: Can We Recycle Helium?
Since we can't make it, the next best thing is keeping what we have. Large-scale users, like universities and hospitals, are increasingly installing helium recovery systems.
These systems capture the helium gas as it boils off from liquid form, compress it, and re-liquefy it. It’s expensive up front, but given that helium prices have tripled in the last decade, it’s becoming a financial no-brainer. If you’re a lab manager or a business owner using gas, recycling is the only way to "make" your supply last.
Actionable Insights for Helium Users
If you are looking at how to make helium because you need it for a project or a business, here is the reality check you need:
- Stop looking for a "recipe": You cannot chemically synthesize helium. Anyone telling you otherwise is selling you a fire hazard.
- Check the Purity: If you’re buying helium for technical work (like chromatography or welding), ensure you’re getting "Grade 5" or "Grade 6" (99.999% or 99.9999% pure).
- Audit your leaks: If you use helium in a commercial setting, buy a high-sensitivity leak detector. Even a tiny pinhole leak in a regulator can cost you hundreds of dollars a month in wasted gas.
- Consider Alternatives: If you’re using it for "leak detection" in manufacturing, see if "forming gas" (a mix of nitrogen and hydrogen) can work for your specific application. It’s much cheaper and more sustainable.
- Support Recycling: If you're in a position to influence a facility's budget, prioritize helium recovery units. They are the only long-term hedge against a volatile global market.
The era of cheap, throwaway helium is ending. Understanding that it is a finite, geological treasure rather than a manufactured commodity is the first step in using it more wisely. We aren't going to "make" our way out of a shortage; we have to engineer our way into better conservation.
