A high school girl in Mexico just won a gold medal for putting out fires with a speaker. It plays one deep, low hum and the flames die in about 5 seconds.
DARPA tried the same idea back in 2012 with a rig so big and clunky they never took it any further, and hers runs on a 12-volt battery and a speaker she can carry around.
Sound is just air being pushed back and forth. A low note at 30 hertz means the air around the flame is flipping direction 30 times every second.
Flames only exist in a thin layer where fuel vapor mixes with oxygen. Shake that layer hard enough and it keeps getting stretched thinner, the heat gets pulled away faster than the flame can make more, and eventually the flame rips right off the fuel. Whatever tears off is too cool to keep burning, so it just goes out.
DARPA's report put a number on how little it takes. Once the air at the flame is moving about half a meter per second, which is barely a breeze, the flame goes out, and pretty much any pitch can get there if you crank the power high enough.
Low notes just get you there way cheaper, because a speaker moves a lot more air on each push when the pitch is low. Two engineering students at George Mason figured this out by trial and error in 2015. They started with super high pitches, 20,000 to 30,000 hertz, and all the flames did was shiver. It only worked once they dropped down to 30 to 60 hertz, which is basically the bass on a hip-hop track.
Ángela Karime's build is a 12-volt battery, a frequency generator, an amplifier and a speaker, tuned to 30 hertz. She named it Vortex Tech and talks about it shooting out little rings of air, and that's real physics. When loud, low sound gets pushed through a narrow opening, the air curls up into rings like a smoke ring, and those rings carry a puff of air way farther than the sound would get on its own. In her tests it put out small flames from about 2 meters away.
She went through five prototypes and over 100 tests in about a year, and she says it's put out burning wood, flammable liquids, electronics and cooking oil.
The cooking oil one is a big deal. Throw water on a grease fire and it flashes into steam and flings burning oil all over your kitchen, which is exactly the kind of fire where you'd want something that doesn't put anything into the pan.
Now, sound can't cool anything down, so a big fire sitting on red-hot fuel can come right back the second the speaker shuts off. The George Mason guys worried about the same thing in 2015, and it's why this is still a prototype for small flames and the red extinguisher under your sink isn't going anywhere yet.
Space might end up being where this matters first. Up there water floats off in blobs, while sound works the same with or without gravity, and acoustics researchers have already published experiments on fighting fires with sound on spacecraft.
She's still in high school, and she's already working on a version that spots a fire and puts it out by itself. The gold in Indonesia also came with a special award that gets her into another international competition.
Profesor ekonomii na uniwersytecie stwierdził, że kiedyś oblał całą klasę. Ta klasa upierała się, że socjalizm działa i że nikt nie powinien być biedny, a nikt bogaty, że wszyscy są równi...
Nauczyciel powiedział im: „OK, przeprowadzimy eksperyment z socjalizmem w tej grupie.
Wszystkie oceny będą uśrednione, a każdy dostanie tę samą ocenę, więc nikt nie oblany i nikt nie dostanie 10”.
Po pierwszym teście oceny zostały zsumowane i podzielone przez liczbę studentów, i każdy dostał 8.
Studenci, którzy uczyli się intensywnie, byli zdenerwowani, ale ci, którzy uczyli się mniej, byli zachwyceni.
Gdy zbliżał się drugi test, studenci, którzy wcześniej uczyli się trochę, uczyli się jeszcze mniej, a ci, którzy uczyli się intensywniej, powiedzieli sobie, że oni też chcą „darmowego prezentu”, więc też uczyli się mniej.
Średnia z drugiego testu wyniosła 6.
Gdy przeprowadzono trzeci test, średnia ocena wyniosła 4. Ku wielkiemu zaskoczeniu wszystkich studentów, wszyscy oblali.
Nauczyciel powiedział im, że socjalizm w końcu zawiedzie, ponieważ gdy połowa populacji widzi, że nie musi pracować, bo druga połowa się nimi zajmie, a gdy ta połowa, która pracowała, zdaje sobie sprawę, że nie ma sensu już pracować, bo inni korzystają z ich pracy, to jest koniec każdego narodu.
Ta historia może być bajką, a nie faktem, ale morał jest prawdziwy.

This Democrat-repeat offender is up for reelection... and wants her mug shot to DISAPPEAR. Well - not on our watch.
Harris County Treasurer Carla Wyatt, a Democrat, has been accused of driving without insurance when she allegedly caused a four-vehicle crash on Interstate 45 last month.
⠀
On September 18 Wyatt’s 2005 Nissan Xterra failed to control speed and rear-ended vehicles in a chain-reaction collision north of Tidwell Road. Police cited her for failure to control speed.
⠀
Drivers say she had no active insurance, told one victim she needed to move because she was late for a meeting, and initially claimed the other cars were stopped. One injured driver reports roughly $10,000 in medical costs.
⠀
Wyatt’s insurance policy had reportedly lapsed in July. Since taking office in 2023 she has been arrested for DWI in December 2023 (dismissed after diversion) and for burglary of a vehicle in December 2025 (no-billed by a grand jury).
⠀
She faces a pending DWI charge from a May 2026 arrest in Galveston County where officers found her asleep in a vehicle on the highway. Wyatt is seeking re-election on November 3.

🚨 ABSOLUTELY NUCLEAR: SCOTT BESSENT JUST HUMILIATED OBAMA WITH A CHEESECAKE FACTORY LUNCH 😂🔥👑
Yesterday Obama was out there sneering at everyday Americans, calling Trump’s White House “Saddam Hussein’s Cheesecake Factory” like some elitist from his Martha’s Vineyard estate.
Today? Treasury Secretary Scott Bessent walked straight into the Cheesecake Factory, ordered lunch, and dropped this line:
“This is the man who built the museum that looks like DARTH VADER’S TOMB! I would tell the Martha’s Vineyard set to give it a try.”
While Obama lectures from his ivory tower, Bessent is eating with regular people. Pure dominance. Absolute LEGEND. 🧀💥
If you’re tired of coastal elites looking down on the rest of the country, smash that repost and drop a 🧀 in the comments.
Correct.
Using Starlink, a civilian commercial service, for offensive drone strikes to kill people has never been allowed, nor should it be.
Starshield, a different system, is controlled by the US government. What they decide to do is up to them.
Ukraine military violated Starlink terms of service and used it for offensive drone strikes to kill people. That loophole was closed last week.
Starlink remains critical to the defense of Ukraine, as it is the only system that cannot be jammed or blown up, at least for now. Were Starlink to be turned off, the Ukrainian front line would collapse immediately. This is NOT a threat, it is simply a statement of fact.
Starlink was also crucial to preventing Russia from overrunning Ukraine in the early days of the war, as all other means of communication were destroyed or jammed by Russia.
SpaceX has done more to defend Ukraine than any private company on Earth BY FAR.
That said, I have nothing but UTTER CONTEMPT for the virtue-signaling evil warmongers who push for endless slaughter and offer no realistic solution to the conflict. May you burn in hell.
End of story.
A PLANE IS ON ITS WAY TO TORONTO , WHEN A BLONDE IN ECONOMY CLASS GETS UP AND MOVES TO THE FIRST CLASS SECTION AND SITS DOWN.
THE FLIGHT ATTENDANT WATCHES HER DO THIS AND ASKS TO SEE HER TICKET.
SHE THEN TELLS THE BLONDE THAT SHE PAID FOR ECONOMY CLASS AND THAT SHE WILL HAVE TO SIT IN THE BACK.
THE BLONDE REPLIES, "I'M BLONDE, I'M BEAUTIFUL, I'M GOING TO TORONTO AND I'M STAYING RIGHT HERE."
THE FLIGHT ATTENDANT GOES INTO THE COCKPIT AND TELLS THE PILOT AND THE CO-PILOT THAT THERE IS A BLONDE BIMBO SITTING IN FIRST CLASS, THAT BELONGS IN ECONOMY AND WON'T MOVE BACK TO HER SEAT.
THE CO-PILOT GOES BACK TO THE BLONDE AND TRIES TO EXPLAIN THAT BECAUSE SHE ONLY PAID FOR ECONOMY SHE WILL HAVE TO LEAVE AND RETURN TO HER SEAT.
THE BLONDE REPLIES, "I'M BLONDE, I'M BEAUTIFUL, I'M GOING TO TORONTO AND I'M STAYING RIGHT HERE."
THE CO-PILOT TELLS THE PILOT THAT HE PROBABLY SHOULD HAVE THE POLICE WAITING WHEN THEY LAND TO ARREST THIS BLONDE WOMAN WHO WON'T LISTEN TO REASON.
THE PILOT SAYS, "YOU SAY SHE IS A BLONDE? I'LL
HANDLE THIS, I'M MARRIED TO A BLONDE. I SPEAK BLONDE."
HE GOES BACK TO THE BLONDE AND WHISPERS IN HER EAR, AND SHE SAYS, "OH, I'M SORRY." AND GETS UP AND GOES BACK TO HER SEAT IN ECONOMY.
THE FLIGHT ATTENDANT AND CO-PILOT ARE AMAZED AND ASKED HIM WHAT HE SAID TO MAKE HER MOVE WITHOUT ANY FUSS.
"I TOLD HER, 'FIRST CLASS ISN'T GOING TO TORONTO."
Volvo’s iconic “Epic Split” commercial starring Jean-Claude Van Damme remains one of the most remarkable advertising stunts ever captured on camera. Before filming, the truck drivers reportedly spent eight days practicing the intricate maneuver, perfecting the timing and positioning of two Volvo trucks reversing in formation. When Van Damme finally arrived, he positioned himself between their side mirrors and performed his legendary split as the vehicles gradually separated. Remarkably, the breathtaking sequence was reportedly completed in a single take, transforming days of meticulous preparation into an unforgettable cinematic moment.
What makes the stunt even more extraordinary is the incredible coordination required to execute it. Both trucks had to reverse at precisely controlled speeds while maintaining perfect alignment, leaving almost no room for error. At the same time, Van Damme relied on his exceptional flexibility, balance, and composure to hold the split as the distance between the vehicles increased. Contrary to the popular myth, his legs weren’t physically keeping the trucks apart. The illusion of effortless stability came from the drivers’ precision, extensive rehearsals, and carefully engineered execution.
The advertisement quickly became a viral phenomenon, combining an astonishing physical performance with brilliantly simple filmmaking. Van Damme’s peaceful expression, the slowly separating trucks, and the dramatic soundtrack created a moment that seemed almost too incredible to be real. Beyond showcasing his legendary athleticism, the stunt highlighted Volvo’s advanced steering technology and the extraordinary skill of its drivers. Eight days of preparation, one unforgettable take, and a commercial that secured its place in advertising history.
It’s insane what’s happening in Ohio right now.
The Ohio Democrats have an army of Somali Muslims who don’t speak English who have been deployed to ballot chase for the Democrat candidates on the ballot.
Amy Acton @amyactonoh and @SenSherrodBrown are trying to turn Ohio into Minnesota.
Don’t let them!
GOTV!
