If Every Second Lasted an Hour, This is What Things Would Look Like

What if every second lasted one hour instead? What would our world look like? Thanks to the powerful technology of ultra-high-speed cameras, here's a fascinating video that shows exactly what things would look like.

The Slow Mo Guys, who have a whopping 14+ million subscribers on YouTube, ordinarily shoot their slow-motion videos at 1,000 frames per second and then play back the footage at 25 frames per second. If you do the math, that means each real-world second captured by the camera turns into 40 seconds of slow-motion footage.

For this experiment, however, The Slow Mo Guys used the insanely fast (and insanely expensive) Phantom TMX 7510 high-speed camera to capture moments at a whopping 90,000 frames per second.

If you divide 90,000 by 25, you get 3,600 seconds, or 60 minutes, or 1 hour. That means every real-world second captured at this frame rate produces one hour of video when played back at 25fps.

"At this speed, a minute would last two-and-a-half days," Gavin Free says. "An hour would last five months. And a day would come in at just under a decade, at nine years and ten months. […] A month would last around three centuries, and a year would be about 3,597 years."

In the video above, we see a number of shots in "ordinary" slow-motion at first before they're slowed down to 1-second-to-1-hour slow motion -- things like watch splashing or falling, a guy falling into a swimming pool, a match being lit, a water balloon being popped.

"Does anyone else get slightly filled with dread imagining how bad it would be to be stuck at this speed," the Slow Mo Guys write. "Even if you were surrounded by people you wouldn’t be able to communicate with anyone. It would be so lonely.

"It would take you so long to move anywhere. You wouldn’t be able to let anyone know what was happening to you. To them you’d be moving at normal speed but acting strangely…"

Watch Vintage Flashbulbs Burst in 100,000 FPS Super-Slow Motion

Filmmaker Ryan McIntyre recently had the opportunity to use the Phantom TMX 7510 slow-motion camera's 100,000 frames per second and combined it with a Laowa 24mm 2x Macro Probe lens to capture spectacular footage of vintage flashbulbs bursting brightly.

McIntyre operates the video production company CineSpeed that focuses solely on capturing high-speed images. He and his company use Phantom high-speed cameras to capture remarkable images that usually happen too fast for the human eye to see. For his most recent project, McIntyre decided to capture close-up, slow-motion footage of vintage flashbulbs bursting, as he had never seen what the reaction looked like from this perspective.

The idea for the film came after he watched a low-resolution video of a lightbulb blowing up. He added it to a list of ideas he had for when he got the opportunity to use a TMX camera in the future. That future eventually came, and he got to work making his idea into reality.

"Our original plan for this shoot was to see if we could capture vintage flash bulbs exploding, but no matter what we tried we could not make that happen," McIntyre tells PetaPixel.

Flashbulbs aren't designed to blow up -- quite the opposite, actually. And despite trying multiple different voltages and extreme temperature changes, McIntyre and his team were unable to make them explode. Despite the deviation from the original plan, they were able to capture something quite extraordinary nonetheless.

"During testing, to our surprise, we captured something much better," he says. "The first extreme shot, when we exposed correctly, completely shocked us when we played back the video. The macro footage seemed almost otherworldly."

McIntyre says that he and his team used two specialty arc lamp lights to light the flashbulbs more evenly and give them more detail in the shadows. Specifically, they used the MR2400 from Megaray. To fire the flashbulbs, McIntyre rigged them to a nine-volt battery, which he says worked perfectly.

"The flashbulbs we used were extremely bright, and exposing correctly for them took some trial and error," he explains. "After a few failed attempts, I decided to close the lens the whole way down and speed up the shutter of the camera to the fastest it could go, and that is when we captured one of the best shots."

The footage seen in the video above required the camera to expose for just 95 nanoseconds per frame, and the lens had to be set to an aperture of f/40.

Watch Sound Waves Shatter a Wine Glass at 187,000 Frames Per Second

Gav from The Slow Mo Guys displays the power of sound by using extreme volumes to shatter a wine glass, all captured with a high-speed camera shooting at 187,500 frames per second.

The Slow Mo Guys YouTube Channel has been producing excellent videos that show different activities captured at high frame rates for years. Most recently, Gav showed what happens when a spark plug hits a car window as well as revealing how an old 16mm motion picture camera works.

Using a Phantom TMX 7510 at 187,500 frames per second, Gav this time shows how playing a wine glass's "least favorite sound" at extreme volumes affects the fragile vessel. "That's around 7500x slower than you can see with your own face," Gav writes.

Gav notes that the resonant frequency of the glass, the sound that you can hear when lightly flicking the side of it, is the same frequency he aims at the glass extremely loudly. Resonant frequency is the natural frequency where an object or medium vibrates at its highest amplitude, according to Cadence PCB.

In this case, glass shatters when exposed to a certain frequency because the acoustic waves of sound cause the molecules to vibrate.

"When projected from a source, the vibration traverses through the air onto the physical structure of the glass," Cadence explains. "If the acoustic frequency of the sound matches the natural frequency of the glass, the latter starts to vibrate at a larger amplitude, potentially disintegrating its structure."

In this case, Gav intends to take advantage of the wine glass's resonant frequency of 505hz and hit it with that sound very closely and very loudly to force the molecules to vibrate wildly, which affects the structure of the glass, causing it to shatter.

"Do not watch this video if you have glass eardrums that resonate at 505hz," Gav jokes.

Gave creates and aims the sound at the glass by playing the chosen frequency on an iPad and through an amplifier that is connected to a two-inch compression driver with a short bit of PVC attached to it, which focuses the sound into the side of the glass.

The camera Gav uses is, as previously noted, a Phantom TMX 7510, which is a relatively new camera that was launched earlier this year. The TMX 7510 achieves 76,000 frames per second at full 1-megapixel resolution of 1280 x 800, over 300,000 frames per second at 1280 x 192 resolution, and over 770,000 frames per second at smaller resolutions — But it gets even faster. Gav's chosen speed of 187,000, therefore, slips in as a nice mix of high speed and decent resolution.
