24 AMAZING OPTICAL ILLUSIONS That Will Trick Your Eyes!

[@physicsfun]

Hello :) Where are you from 🌍? How many of you guys watched full 15 minutes long video! Did you guys like 15 minutes format?

[@yannfalcon3576]

France yes. Good and beautyfull vidéo continue like it 😉 please

[@itsRakesh]

Hey! I'm from India and I'm watching ur vids for a long time!!! Keep up the good work!!

[@yannfalcon3576]

Yo

[@anhadorigamichannel9800]

India pls shout me out love your vids

[@imnoob7002]

Yes

[@teacherhaggis6945]

Final puzzle: There is a film of air between the plastic sheet and the pictures of the animals. The mirror effect is caused by total internal reflection; the incident angle, as measured from the normal, is greater than the critical angle. Great puzzle; I enjoyed it. Cheers!

[@bharathireddywari2378]

Bonus clip is unbelievable

[@feelpleased3619]

The science toys are wonderful, fascinating and mesmerizing. Teachers would want to bring them to the classroom for their teaching. Students must become interested in science, especially in Physics.

[@akilansritharan2415]

One word : Mindblowing !!!

I like your video from France

[@chandrasekharrandhi]

Nice work 👍

[@mrunalmotghare9224]

I showed this video to my daughter who is 7years old , thought she will learn something😇but now she is literally killing me with her questions why?,how? what?😌I really don't know how to satisfy her🙄

[@carollafontaine7690]

Saw some of those before. Thanks.

[@037bkousikeebasu6]

This is absolutely fantastic 👌...loved it...from India...

[@T39Omi]

It's due to critical angle and the angle of refracted light is greater than critical angle

[@jimmyvalentine8690]

Yeah i also think so

[@dikvikjain3617]

Awesome videos, these eye illusions are possible if looked carefully. I have got the solution of one 11 : 19... This is because their is one light between two mirrors. They infinitely reflect the light.

[@chrisjohnson2460]

WOW, very cool!

[@physicsfun]

Thanks!

[@so-qwev8346]

I am enjoying lockdown by watch your videos.

Glad to hear it!

I love this channel!

7:06 when someone says, “You’re almost there! You can do it!” EDIT: Also, There’s always a light at the end of the tunnel. The tunnel: 11:19

It might be a train why knows

Glad to hear that ❤️ Everything in this world can be understood through math and physics.

So super nice

[@AvijitMaity_naruto]

Wow nice 👍

[@TeamFTPLEO19]

The skye blue cafe wall illusion trick is , keep watching that illusion for 10 secs it look horizontal

[@MushookieMan]

The plastic on one side has a lower refractive index than the salt-water in the bowl, so total internal reflection occurs in the water. The worms are printed on the outside, so you can still see them.

[@vishalvarma2438]

i am from india and love your videos. the answer to the question is because of the refractive index that changes in water

[@kritantasasanroy]

Awesome nice love you jio guru tusi chagaye means you are popular world wide

[@DivaDiamondDavenportMahogany]

Maybe, is the way the card was made. In this case, one side of the card has the same transparency of the water, i suppose.

[@SHEensya]

😱 awesome stuff!

[@anandsinghrawat2722]

The sea creatures are printed in shiny card and worm seperately so that sea creatures disappear when they immersed

[@egroegknimmij3169]

7:33 liked that

[@physicsfun]

Glad you liked it The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

[@mandybranch7218]

England n yep watched the whole video, loved the bonus content... Starwars very clever 🙂

Glad you enjoyed it!

WOOOOOW! 🤩

[@dreadnoughtus2598]

Ghost of Einstein would be better if it spun slowly on its base

[@ANAND...TIWARI]

Amazing! Really!

[@biacullajosu]

Can it be due to the light dispersion of the air buble inside the plastic?

[@TheHippyDragon]

An answer for the fishing illusion: Everything is printed on the foil base. Everything BUT the shark, octopus, and "WOW" is printed again on the plastic film that is coating the foil. you can see the "dual" printing effect on the closeup. So the shark, octopus and "WOW" are hidden behind the plastic.

[@purplealice]

Lenticular image, and the clear plastic has an index of refraction equivalent to that of water

[@junejuly532]

The 3d lenticular logo is my take. How is that made?

[@smartytarim]

[@theeternal7970]

How to prepare them ?

[@purplealice]

The sea creature pictures are covered by a ridged layer of plastic. The water fills in the valleys between the ridges, refracting the images to an angle where they aren't seen.

[@binashah3106]

love u from nepal

[@sivamanir9812]

How to make this or buy it please

[@IsaacDueck]

What about the video explaining the things in the last one you made?

[@StudentWalaGamer]

8:17 How it is possible?

[@MrJdsenior]

2:40 SHOULD be award winning, superb illusion! Why the sea creatures disappeared? EASY!!! It's a conspiracy by the worms. ;-)

[@i_akshaybabu]

It is due to refractive index thae same thing which cause us to unable to calculate the depth of a well

[@samanwaymridha4890]

The part of card has the same refractive index as water so we can't see that in water

[@purplealice]

"In or Out" - one arrow points straight up, the other straight down

[@Dev1nci]

Wow! Wow! Yaw! Zaw!

[@fasihullahsaleem]

Brain teaser answer when you put card in water the reflection angle is changed

[@kanzariyanimeshmanojbhai3154]

Light from fish do not have reflect in water because water reglective index greater than air

[@tvvelvegauge12]

That first one should of had an S symbol inside of it...notice at one angle it looks like the shape of Superman's insignia...

[@pedroraulojeda9479]

Increíble!!!!

The sea creature dissapear because of refraction of light. Which bends thr light away from our eyes.
