This is a story of a box truck and its bouncing baby box. An automatic transporation-focused Twitter bot named @tw_kotsujiko run by @90ntyan posted an amusing video this week of a storage box falling out of a moving truck and bouncing back into the truck's cargo area. What seemed to be a trick or prank of some sort was likely the result of a perfect blend of air flow and pressure that directed the box back to its home.
Via Jalopnik, the video was filmed on a highway in Asia. The box truck is seen driving with the rear door open and several pieces of cargo inside. Specifically, there appears to be at least three mid-sized boxes made of cardboard or styrofoam.
At six seconds in, the box falls, hits the pavement, does some flips, and drops right back into the truck. Then it falls off again, bounces again, and perfectly places itself in the corner of the truck, aligned with the other boxes. Despite the opportunity to venture into the great outdoors, the young box simply coudn't muster the will and might to leave the nest.
The text attached to the video roughly translates to, "certainly there is a Karman vortex behind the truck." A second translated comment reads, "Some people are debating Kármán vortex and slipstream, but they both mean the same phenomenon. The former is the 'vortex' that can be formed behind, the latter often refers to the act of using it." According to NASA, "von Kármán vortices arise when winds are diverted around a blunt, high-profile area," a phenomenon first described by physicist Theodore von Kármán in 1912.
We're not qualified to detail the exact science behind it, but basically the box, which apparently has nothing remotely weighted inside, falls out, is kicked up by one air stream, and is kicked back in by another. *Aaron Paul voice* Yeah, science!
In rural Poland, an unidentified motorist celebrated Easter by launching a third-generation Suzuki Swift off a roundabout and into a building owned by a church. The jump was captured by a security camera.
Polish news site Remiza published the 20-second video on its official Twitter account. The resolution is on par with what you'd expect from a security camera, but we can clearly see the gray, four-door Swift approaching the roundabout way too fast about eight seconds into the clip. The driver seemingly tried to make an evasive maneuver, but it was too little, too late. He went straight where the road didn't.
Wczoraj po godzinie 18:00 doszło do nietypowego zdarzenia w miejsowości Rąbień. 41- letni kierujący samochodem osobowym wjechał na nasyp ronda i ... poleciał wprost na zabudowania przykościelne. Kierowcę trzeba było wydobyć z wraku za pomocą hydrauliki. Prawdopodobnie był pijany. pic.twitter.com/xpuQaVbpya
He hit the stone embankment, which was luckily sloped rather than perpendicular to the road, and it pelted the Suzuki into the air at an angle we thought was only possible in Grand Theft Auto. He snapped a tree in half, allowing the local fire department to calculate he got about 23 feet off the ground, and flew for 209 feet until he hit a building that's part of a church. It was sturdy enough to end his impromptu flight.
Suzuki didn't design the Swift to fly, so its landing was about as rough as it sounds. First responders used the Jaws of Life to cut open the hatchback and extract the 41-year-old driver. Remiza wrote police officers said the man smelled like alcohol, though the results of his breathalyzer test haven't been published. He was hospitalized, and the mangled, cut-up Swift was hauled away to the nearest junkyard. No one else was injured.
