Mechanical engineers at Pennsylvania's Lehigh University are, [per a press release](), using Hellmann's Real Mayonnaise — yes, they specified the brand — as a stand-in for plasma, the [highly-charged state of matter]() that occurs when electrons are shed during the collision of atoms. Neither solid, liquid, nor gas, plasma is believed to hold the key to fusion power, which despite [various]() [steps forward]() remains impractical for [generating power at scale](). Arindam Banerjee, the mechanical engineer who led this experiment at Lehigh, and his team are experts in what's known as inertial confinement fusion. This discipline aims to heat small capsules filled with fuel (in this case, hydrogen isotopes) to Sun-like extreme temperatures, which then melt and become plasma. ## Fused and Enthused As one might expect, melting down hydrogen can create some wildly unstable conditions. To simulate the process, Banerjee and his team decided to use mayo, which as the scientist noted "behaves like a solid, but when subjected to a pressure gradient, it starts to flow." One needn't subject Hellmann's to Sun-like temperatures or pressures to get it to melt, either. Instead, the mechanical engineer and his colleagues built what they called the Turbulent Mixing Laboratory, a huge contraption that whipped the condiment rapidly until it entered a plasma-like state. "As with a traditional molten metal, if you put a stress on mayonnaise, it will start to deform, but if you remove the stress, it goes back to its original shape," Banerjee explained in the press release. "So there's an elastic phase followed by a stable plastic phase. The next phase is when it starts flowing, and that's where the instability kicks in." Obviously, rapidly-spun mayonnaise isn't the same thing as plasma. But the scientists behind this new research, [published in the journal *Physical Review* *E*](), hope that they can scale up the findings by orders of magnitude and try to translate it when trying to achieve fusion. "We're another cog in this giant wheel of researchers," Banerjee said. "And we're all working towards making inertial fusion cheaper and therefore, attainable." https://youtu.be/ql2R0AX2yN0 **More on fusion:** [*MIT Claims Superconducting Breakthrough Means Fusion Power Can Be Practical*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
