I am no expert at all but if you combine that laser with a bright light that illuminates the room at a specific frequency the light could make the laser look less intense infront of the now light up background. A bit like the floating water experiment but in reverse. But it might not work this way since the other experiment works with the absent of light and this with the addition. Means the eyes will probably just "fill" the time with no light and therefore no visible effect. But what about this effect with 3d glasses that open and close? Very likely it is open for too long...

You're definitely more than just the guy turning the camera 90 degrees to get a good angle and the guy driving people around to catch up with their space garlic. You're the guy bringing all of these weird and wonderful community inventions to the public eye. Thank you Tom Scott. You're amazing at what you do x
Only thing that disappoints me about these things is that you can't do it for a human eye, normal displays that rely on tricking the eye via high speed only put light where it's wanted, while this relys on ignoring all light except a specific part so that spiral effect probably looked like a cone irl.
If I were to guess I’d say they likely didn’t use glasses while filming because it looks better. I mean if u were to learn how to backflip you’d probably want a mattress under u but when u show the video to your friend u gotta be landing one on the grass.
yes, and actually many film cameras had rolling shutters too, especially the ones for stills-it was the dominant kind for the 35mm format rotary shutters for movie cameras were also common
@@666Tomato666 Even today in digital cameras, especially professional ones like RED cameras, the metric of shutter angle is still used, a combination of shutter speed and framerate. This is a remnant from rotary shutters. A shutter angle of 90° means that the exposure time is a quarter of the time each frame represents (at 24 FPS, the standard in movies, that's about 40 milliseconds per frame, so 10 milliseconds of exposure time). This is because with a rotary shutter, 90° is a quarter of the disc, and the shutter disc makes one revolution every frame, therefore the film is exposed for only a quarter of the time of the frame. Film cameras and rotary shutters are used less and less of course, but shutter angle remains as standard terminology.
Yup, and doing some quick googling the cost for a camera is several thousand to over $10,000 That doesn't even come close to the cost the broadcast lens which can cost over $200,000.
@@Dysan72 actually there are far cheaper options, like Black Magic Production Camera 4k that offer global shutter there are also rolling shutter cameras that have very fast readout (
@@Dysan72 The optics are the biggest factor in the added cost as CCD sensors are less sensitive than CMOS sensors mostly because of the benefit which results in rolling shutter being used namely that the rolling shutter allows the sensor to continue collecting light during the readout. CCD sensors need to be kept in complete darkness for the entire duration of the readout of every pixel thus less effective exposure time per frame and less sensitivity so you need a larger aperture and thus larger lenses etc to be able to deliver good performance over a range of different lighting scenarios.
So what you're saying is if we had camera shutters over our eyes we could have light projections in the air that become holograms when calibrated. Got it.
@@thesuperginge1348 well the glasses would need to be huge, or at least something like the google glass since it need a camera and a display in front of your eyes so you don't see anything else around your fov
@@heatshield ? no he's not, 3d glasses use 2 different LENSES to trick your mind into thinking the two images on screen are not 2D, but for this to work you need CAMERA SHUTTERS since the laser is constantly going and depends on the shutter of the camera for the illusion.
The way you do bullet-time dodge is you shift your weight to the insides of your feet (laterally) so you're essentially balancing on the inward sides of your feet, you angle your feet outwards and put a massive load on your ankles, then proceed to balance backwards. The footwork is what makes it possible... Is also a limbo trick.
Once you started playing around with it, I figured it was practical effect or camera trick, but still cool. However, light only travels at c *in a vacuum*, and I know there's been work in laboratories where you can reduce the effective speed of light in supercooled noble gases down to human speeds, which would also be a really cool video
It *can* be done... If the train is only moving at about a millimeter or two per second, it's engine is not engaged, you're really strong/have a lot of endurance, and you are on a long straightaway on flat ground.
That's easy. I could do it with one hand. Although I wouldn't want to, because I'd lose the hand. It works like this: you stand by the tracks, as the train approaches you reach out a hand and SLAP that mofo in it's little train face. so your hand starts out travelling at, whatever, say 10mph towards the train, then as the train hits it at 40mph in the opposite direction, the hand slows down, stops, and reverses direction. It has to stop in the middle, it can't go from 10mph to -40mph without passing through zero. It passes through zero mph at a time when it is in contact with the front of the train, therefore the train must hit zero mph too. And that's how you stop a train with one hand. But, like, you probably shouldn't.
I was disappointed to learn that it _is_ a camera trick. I was hoping for creature use of interference or something. If you out your hand between the "stationary laser bolts" you will still cut off the laser. Still, fun to learn something new.
0:39 As a note, Kylo could stop a Star Wars blaster bolt, as it is technically not a laser. Apparently it is a super heated gas (so basically plasma) that is then launched at what you want dead. Therefore, blaster bolts in star wars are matter, and could be affected by the gravity like forces of the, well, Force.
I'm 30yrs old, and I'd already been a lifelong fan of Star Wars before TFA released, but actually seeing Kylo freeze that bolt mid-flight absolutely blew my mind. Yes I knew it was something that could be done, but actually seeing it in all it's silver screen glory was truly something else.

I think Styropyro might want to have a word with everyone in that room not wearing laser goggles at all times while those lasers are on... 3:20 and 5:02 look particularly sketchy.
@@the_retag class 4 lasers are dangerous even when looking at a diffuse reflection (off a wall for example). It's usually only dangerous a small distance away from the diffusing source but still...
I think alot of "laser" weapons like the ones in star wars are actually plasma weapons rather than a beam of light. Essentially a superheated glob of gas being shot.
Jim Stanley At intensities much greater than that of the laser Tom stuck his hand in front of. They cranked it up at the end and Tom could feel the heat just standing next to it. It burned the wall it was pointed it at by the look of it. _That_ intensity could’ve damaged his retina even after subsurface scattering.
Actually a blaster bolt can travel slowly enough as it is energised plasma, not a laser. Ren could stop it as it is a physical object rather than projected energy as pure photons.
I will never...ever forget a night club in Bournemouth circa 1992 or possibly 1995. I have never seen a laser show like it before or since. The club was opposite a church with a graveyard. I was blown away, totally.

i wish i could do this but instead of in real life it's in the legend of zelda breath of the wild and i'm against 4 guardians
[Piano intensifies]
You realise its not actually happening? its just a camera trick. that guardian laser will still light you up lmao
@@daveski7 well i dont think calamity ganon is happening either
@David Turner i didn't imply that it was but ok
I was wondering why the quality of the "1080p" video was like that!
*Dude to Tom* : You’re ruining my test now.
*Me, feeling defensive for Tom* : Okay no need to be a jerk about it.
I felt the same. The dude seems like a passive aggressive prick.
Must proteccc
Absolutely love this! Especially the guy taking the laser to the throat at the end!
I already know how this works but I am still watching it anyway because it's Tom Scott
I think Styropyro might want to have a word with everyone in that room not wearing laser goggles at all times while those lasers are on...
3:20 and 5:02 look particularly sketchy.
The lasers are mounted solidly so that may amke it a bit safer
@@the_retag probably not, lasers are extremely finicky.
@@the_retag class 4 lasers are dangerous even when looking at a diffuse reflection (off a wall for example). It's usually only dangerous a small distance away from the diffusing source but still...
@@the_retag When somebody or something interacts with the laser the reflection can be unpredictable, so no, it's still not okay
I read all of these comments with Styropyro’s voice
Styropyro: Hold my microwave transformer.
I think alot of "laser" weapons like the ones in star wars are actually plasma weapons rather than a beam of light. Essentially a superheated glob of gas being shot.
Plasma, while technically is ionised gas, is more specifically a separate form of matter to gas.
The original matrix bullet dodge wasn’t even slow mo, it was filmed by several cameras in a circle simultaneously.
It wasn't even real bullits.
Definitely the coolest video you've done
"This can burn your retina out"
Sticks hand directly into laser
Your retina isn't in your hand.
@@ErwinPommel class 4 laser can burn your retina reflecting from a diffuse object.
@@ErwinPommel Now that's a damn scientific statement if I've ever heard one
@@ErwinPommel straight facts
Jim Stanley At intensities much greater than that of the laser Tom stuck his hand in front of. They cranked it up at the end and Tom could feel the heat just standing next to it. It burned the wall it was pointed it at by the look of it. _That_ intensity could’ve damaged his retina even after subsurface scattering.
I do feel after watching this that I should note that the blasters of star wars shoot stuff more akin to plasma bolts than actual lasers
Actually a blaster bolt can travel slowly enough as it is energised plasma, not a laser. Ren could stop it as it is a physical object rather than projected energy as pure photons.
I will never...ever forget a night club in Bournemouth circa 1992 or possibly 1995. I have never seen a laser show like it before or since. The club was opposite a church with a graveyard. I was blown away, totally.
Tom: [fails the bullet dodge]
Morpheus: "Maybe we should keep looking for the One."
>this video in my reccomended
>Name “tom scott”
Me: “this guy has a british accent this guy has a british accent this guy has a british accent
Tom: Hello
Me: AHHHHHHHH-
where is the funny
