I found this link later that night while fishing. twitter.com/smartereveryday
I have one question: Why you have red googles when you play with green laser, doesnt you need green googles? Nevermind, great video!
San Samman i think you need to find out for yourself😂😂
what happens if you were to record the internal reflection of the water from the outside *while making waves in the water* ? would bounce into and out of internal reflection due to the changing angle of incidence (since you would be making waves)?
Congratulations, you managed to leave 4 fish permanently blind with your little laser stunt... I'm here to serve you their civil lawsuit papers... You have 35 days to respond. Later
In regards to the acrylic rid, It's actually not a fibre optic, but rather an optical fibre :-)
Indeed, and in a public swimming pool, where the water is super wavy, its super easy to see.
4:54 Thats a Double Helix!
6:56 "You got the BFG-9000!"
I wonder if the fish are asking wtf us going on up there
Safety glasses on 😲
What is that beard man
At first you had me then I was like "who brings an acrylic block and lasers fishin?" 🤔
I love how you’re not doing it in a pool and you’ve brought everything out to a lake and packed up a kayak with it all 😂😂
LAMINAR FLOW!
looking through snell's window kinda creeps me out...
wheres mah lezzer? *laughs maniacally*
I don't know how to explain this but you have made me have a joy that I haven't had in a lot of years. You have made an old man have that wonder again. Thanks!
sharks with freakin lazers attached to their heads
I've never seen someone so excited about angle of incidence but It makes me incredibly excited as well!
Just Mercy also illuminated my mind. Thanks for mentioning it!
Got an ale elk physics test on this tomorrow
What if you put the shine the laser on the side of the fiber optic?
What if you shin the laser on the side of the fiber optic
Bye
Milf oil in the water? The ladies been swimming there before you got there?
Five miutes later: Uh, there's Milf oil in there! That makes it even more fun!
Why do you have to where those glasses
have you noticed he always wears the watch
Lots of blind fish and gators 🐊 after this video 😳
So one could argue, that Lasers are kinda like... _laminar flow..._ for light.
That explains why Destin loves them so much.
7:55 "I'm gonna quit talking"
*Literally 2 seconds later*:
*STARTS TALKING*
Me(While walking away):Just that it would sound way better if you said "optical fibers"
8:20 *shoots him*
Please Use glasses before the watching this video o_o
:D I love you man
God those frogs must shut up
9:06 cool!!! Ypu can see the laser in the pitchblack flying around
Light amplification by stimulated emission of radiation 🤓
Why does he need the goggles?
Very similar to ultrasound used for weld inspection.
can someone tell me what kind of laser that is?? I want one
Nerd
I think you'll love Snell's law Destin
Did 😎destin say... "i even got some milf oil in there" ? 😂😂😂😂😂😂😂😂😂
at 12:00 min is that an animal or car behind him?
to the left of the frame
Anyone else get the willies whenever he put his hand down into the water?
> sitting in the dark
> only source of light is headlamps
"hey lets stick them in the water"
What about air and vacuum
Could we find a way to bounce stuff off the top of the atmosphere? If it’s possible, the atmosphere meeting vacuum would probably be too much of a gradient to work.
Angle is 44.35° propylene glycol 1.4310 air 1.0003 Critical angle = arcsin(1.0003/1.4310)
3:20 for a nice sound byte.
whole video i was thinking please no alligator please no swamp monster
When you do the laser in the ornament, you see a cardioid. I thought that was cool.
Could have just used a fish tank on your kitchen counter with no danger of capsizing...
Is it just me or with the dirt particles in the Christmas ornament with the laser it actually looks like a freaking constellation?
This is Fantastic and amazing however be mindful of pointing that laser up in the sky... we as pilots (Instrument student) has gotten hit by those kind of lazers. Interesting to see how this affects us in the cockpit. This is pretty cool though, that's how inside. Except it does bounce in the cockpit which is frustrating and dangerous for us especially when we're on the final approach. Clear Skies, I appreciate both channels.
Coming back months later because your enthusiasm and joy always makes me smile. :)
Me when fapping 10:31
Smarter every night!
11:48 You couldn't do that in the UK, pretty sure it's flat-out illegal to point a laser at the sky, certainly during the day, for fear of potentially blinding an airplane pilot... doing that would land you 5 years in jail. Though I wonder, if you were accurate enough, do you think people on the ISS could see a laser emitted by a handheld laser pointer from all the way down on the surface?
That's cool my now my question is what do you do with all of that MILF oil you collected?
Did he actually just say, "You can tell it's an Aspen because of the way it is,"?
I have one question: Why you have red googles when you play with green laser, doesnt you need green googles? Nevermind, great video!
Mateusz Czerniawski It has to do with the depth of the film on the goggles making the light interfere destructively, thus you won’t see that certain wavelength of light.
You can tell it’s an aspen by the way it is.
Growing up on Florida's Gulf coast, we did a lot of diving-won't forget the day I first noticed my light beam refracting off the underside surface.
Always love it when I learn a new word, or a different usage of a word I already know-meniscus I was like, "Okay, I know I have a couple menisci cushioning my knee...Google, google, "Oh, cool, a physics term too."
