When goo stops being chill
We Know Simple Fluids Can Flow. Turns Out, Some Can Fracture
Scientists heard a liquid go POP, and the comments instantly turned into jokes, doubt, and outrage
TLDR: Researchers found that a thick liquid can suddenly snap instead of simply stretching, which could change how scientists think about how liquids behave under force. Commenters split between toy-like jokes, homebrew physics theories, and anger that Exxon-backed research is behind the discovery.
A lab test meant to stretch a thick black liquid into a thin strand turned into a wait, did the goo just snap? moment. Drexel researcher Thamires Lima says the fluid didn’t simply ooze and thin out like honey would — it made a sharp crack and broke apart, more like a brittle object than a normal liquid. That surprise has scientists rethinking a basic assumption: some liquids may not just flow under stress, they can fracture.
But the real entertainment came from the peanut gallery. One camp instantly went into "is this just Silly Putty?" mode, with commenters comparing the whole thing to classic toy behavior and wondering whether this is really shocking at all. Another jumped straight into armchair physics, arguing it might be less about some deep mystery and more about speed, force, and inertia — basically, pull something hard enough and of course the weakest point gives out. Then came the resident fact-check energy: yes, one commenter brought up glass, only to immediately run into the classic internet correction spiral that glass is not the same kind of fluid here.
And then the thread swerved into full moral drama. Because the work involved Exxon Mobil, one commenter called the whole thing "dark," blasting the fossil fuel industry for funding exotic materials research while climate damage keeps escalating. So now this story isn’t just liquid goes pop — it’s science surprise, comment-section comedy, and a side of ethical rage all in one.
Key Points
- •Drexel University researcher Thamires Lima observed a simple hydrocarbon fluid fracture during an extensional rheology experiment conducted in collaboration with Exxon Mobil.
- •The fluid was described as nonelastic and simple, making the fracture unexpected because such fluids are generally expected to flow rather than crack under stress.
- •Lima repeated the experiment multiple times, and the material fractured each time, confirming the effect was reproducible.
- •High-speed camera analysis led the researchers to characterize the event as a brittle fracture similar to failure modes seen in brittle solids.
- •The observation challenges the earlier view that elasticity is required for liquid fracture and revived interest in Daniel D. Joseph’s theory that any liquid may fracture under sufficient conditions.
