How Kid’s DIY Nuclear Fusion Project Ended Up On FBI’s Radar
As a tween, Jackson Oswalt had an epiphany that sparked his passion for science.
Jackson was 12, not 22, not 42, and definitely not the kind of kid you expect to be chasing nuclear fusion. He was the kind of kid who watched YouTube at night, dug into how fusion works, and then started building his own setup like it was a weekend LEGO project with a much scarier label.
He documented everything, from vacuum chambers and pumps to a neon sign transformer and a homemade AC-DC converter, and he even rolled the dice with a school science fair demo that he swore he only got working the night before. Then, right before his 13th birthday in 2018, his experiment was verified by Fusor.net, making him the youngest person to achieve nuclear fusion. That should have been the end of the story, except it was also the start of the weird part.
Because not long after the verification, a Saturday morning brought two visitors who absolutely did not belong in a school science fair story, FBI agents.
At just 12 years old, Jackson set a Guinness World Record.
Jackson started where most curious minds do: YouTube. He devoured videos explaining nuclear fusion, researched the materials he’d need, and slowly began putting together his own setup.
If you’re not exactly a science whiz, here’s a quick breakdown of what nuclear fusion actually is. It’s the process of fusing atomic nuclei under extreme pressure and heat, creating new atomic nuclei and releasing a massive amount of energy in the process.
In other words, it’s the same reaction that powers the sun. Not exactly the kind of thing you expect a 12-year-old to be messing with in his garage.
Jackson documented his journey on Twitter, explaining his first step: “The first step was to build a ‘demo fusor,’ or a device that creates plasma but doesn’t achieve fusion. This required a vacuum chamber, vacuum pump, and a neon sign transformer with a homemade AC-DC converter.”
That first version of his project made its debut at his school’s science fair, though he admitted it was a close call: “I only got it working the night before. In hindsight, it’s amazing they let me walk in the door with it.”

One day, he experienced a sudden epiphany.
Over the course of a year, Jackson kept refining his setup, ordering materials, troubleshooting problems, and testing his theories. Then, just one day before his 13th birthday in 2018, he finally succeeded. His nuclear fusion experiment was officially verified by Fusor.net, The Open Source Fusor Research Consortium, making him the youngest person ever to achieve nuclear fusion.
Let that sink in for a second. While most kids his age were worried about middle school drama, Jackson was building a functioning nuclear reactor in his garage.

Before the FBI ever showed up, Jackson was already living online, posting his “demo fusor” progress and chasing fusion like it was a boss level.
If setting a world record at 12 wasn’t crazy enough, things took another unexpected turn not long after his success.
One Saturday morning, Jackson was greeted by two unexpected visitors: FBI agents.
Apparently, word had spread about his little science experiment, and federal agents wanted to ensure he hadn’t accidentally turned his house into a radioactive hazard. They swept his home with a Geiger counter, checking for any unsafe radiation levels.
Luckily, everything was under control, and Jackson walked away with a great story to tell. “Fortunately, I remained a free man,” he later joked.
Once he got the setup running, verified by Fusor.net, the project stopped being a private experiment and started sounding like a headline.
Without proper oversight, children might inadvertently engage in risky or illegal activities, as seen in Jackson Oswalt's case.

And when Jackson’s school science fair almost didn’t happen, that “close call” detail is exactly the kind of thing that makes people talk after the fact.
Seven years later, Jackson’s curiosity hasn’t faded—it’s only grown. Now working at research labs like Midjourney, he applies the same drive that led him to build a fusor at 12 to hardware development and AI research.
What started as a quest for something more exciting than video games evolved into a genuine passion for discovery. Jackson’s story shows how a single spark of curiosity can transform into meaningful work that pushes the boundaries of technology.
That Saturday morning, with two FBI agents at the door, the garage experiment turned into something far more complicated than neon signs and vacuum pumps.
As children delve into scientific pursuits, it's crucial for parents to strike a balance between encouragement and supervision.
Parents can facilitate this by providing resources and mentorship while ensuring that young experimenters understand the potential consequences of their actions. Incorporating hands-on projects with adult supervision can transform risky endeavors into valuable learning experiences, ultimately fostering both passion and responsibility.
Jackson Oswalt's ambitious DIY nuclear fusion project serves as a poignant reminder of the critical importance of guidance in the realm of youth scientific exploration. While the drive to innovate is admirable, it highlights the necessity for a supportive framework that encourages creativity within safe boundaries. The incident raises questions about how young minds can pursue their interests without jeopardizing their safety or attracting unwarranted attention.
Clearly, a cooperative effort between parents and children is essential for nurturing curiosity responsibly. This balance not only fosters innovative projects but also imparts valuable life lessons about responsibility and the implications of one’s pursuits.
He proved he could fuse atoms, but that was the easy part compared to what came next.
