The Slow Mo Guys have captured some amazing things for their YouTube channel—including this amazing footage of glass shattering at 340,000fps—but their latest creation might be our favorite yet. Click play to see a firecracker explode underwater at a mind-bending 120,000fps.
Like their glass shattering video, this footage was captured with the Vision Research Phantom V2511, which allows them to capture unimaginably high frame rates while keeping quality acceptable.
In fact, at 28,000fps, they’re still shooting nearly 720p.
By the time they speed it all the way up to 120,000fps, they’ve dropped below even standard definition, but the resulting shot makes the low res totally worth it. They actually captured it twice, once at f/11 and once at f/2.8 so you can see all aspects of the explosion clearly.
In total, that explosion they captured lasted just 0.010004 seconds but they can stretch it out to a total of 50 seconds at 24fps. Bonkers.
Check out the video up top, and be sure to stick around till the end because they do another test where they focus the camera on the surface of the water so you can see how it reacts to the explosion. It’s not quite as mind-blowing, but still a great way to kill a few minutes at your desk this afternoon.
It’s Friday. The perfect day to share something that’s part camera-related, part science-related, and part this-is-just-plain-cool-related: a hand-held explosion captured at 20,000fps.
Editor’s Note: As with anything fire-related or dangerous, and spud guns are incredibly dangerous, please do not undertake anything similar without first looking up local laws and taking proper safety precautions.
The video was created by YouTube channel SmarterEveryDay, and while there’s no way to say “slow-motion spud gun footage” without sounding silly, it really is both visually and scientifically fascinating. In fact, it may be the most mesmerizing thing you’ve seen for a while.
Photographer Nao Tharp of Los Angeles, California, just released this short video that shows something neat he captured on a freezing cold winter night back on December 12th, 2015. While shooting a time-lapse of the Geminid meteor shower at Red Rock Canyon State Park in California’s Mojave desert, his camera caught a bright meteor explosion and a resulting orange glowing plume that lingered for about 40 minutes.
The video above shows the same explosion at different magnifications and playback speeds.
“It was a bright spark illuminated the entire rim of eroded sandstone canyon, followed by orange fume floating in the sky,” Tharp tells PetaPixel. “According to my calculations based on the time lapse setting and EXIF data from the resulting images, the glowing orange fume floated in the air for a matter of 38.5 minutes until it framed out.”
Here’s the science-y explanation behind what you’re seeing:
“As the icy particle of the meteoroid about the size of a sand grain enters the Earth’s stratosphere at a such high speed, it explodes and turns into plasma due to atmospheric friction,” Tharp says. “The energy of the plasma stimulates molecules of the air and forces them emit photons, resulting in the glowing fume-like particle that floats in the sky.”
