"Woah, you're twisting my melon, man" "does it only work with einstein?"

@MichaelWarbux 13 лет назад

I like how it's turning clockwise with the face out, and then when the face is in, it's turning counter clockwise. That's a 2nd mind freak right there!

@Matthew-ut6ed Год назад

If you force yourself to look only at the flat edges when the inverted side comes round you can see that it is still rotating clockwise, but because your brain inverts the face because it "must" be projected towards you it also appears to reverse the direction of turn.

This is all so CUTE! :D All of them so exited and amazed, like they were still 5 years old and hearing about the space for the first time. Why can't we have shows like this in Finland!? T^T

@AgentDexter47 the light source is behind the mask and to the right. When the face is recessed, the shadow is on the back surface and because the mild is semi-transparent, you're seeing the darker areas through the plastic. So at 0:19, you're looking at the back of the shadow.

@sophieameliaaa 13 лет назад

i love QI it's one of the many things i love about being from England...

@MyLastSiege 13 лет назад

this is awesome

@MythicSuns 2 года назад

It looks like shadows play a fairly big part in this illusion too, I have a feeling this illusion wouldn't work so well if the directed light was more central (the kind of effect you usually get from attaching a ring light to a camera. I'm also pretty sure this effect was utilised in the music video for Fade to Grey by Visage).

@liveshotsvideoproductions 2 месяца назад

Side-lighting enhances the 3D contour of faces, with a frontal light it wouldn't work. That's why I never photo or film people with a camera-top flash or light - it flattens all their features.

@marbleberry1 13 лет назад

i LOVE this video (good thing i don't skip, heehee)

SAY CAKE!

@dunbar9finger 12 лет назад

@mrf71629 This is true. It does work better with a thin translucent sheet that makes it hard to see if the shadow is on the front or the back of the flat part of the plane. (Also, it works better if the object doesn't' have a flat part at all to cast a shadow onto - i.e. if the shell contained only the face and the flat part was cut off.)

@GeorgyE6 13 лет назад

@BrighterLater0 11 лет назад

Good idea

@nitsua101 12 лет назад

@Devoti yes..... yes i did

@kisbie 11 лет назад

The mould is slightly translucent, to allow the light to shine through it. The shadow is coming through from the other side. The light source is in front of the camera.

@jaysmesa 9 лет назад

Pretty awesome

@Kisioj 12 лет назад

@CloudNine201 the shadow is on the other side but you can see it because of the material

@xLucy_Hx 13 лет назад

Saw this on Iplayer already :D

@Arborist5851 13 лет назад

@alienguy5413 11 лет назад

QI is so awesome

@Jamaicobs 11 лет назад

Thank you for being original with NerdCubed jokes and not just saying "I WAS SENT HERE BY [terrible joke relating to nerdcubed content]!"

@VanguardDragon 12 лет назад

@soccer13pro2007 The material is probably translucent, so the shadow cast on the other side is visible on the side facing us.

@Skaterdude518 13 лет назад

@Jimanjee21 It's actually just the shadow to the extruding part from being bit you can see it because the plastic is transparent

@Oivoi 12 лет назад

@mesden it's the shadow on the other side. the light shines through the mold.

@dimitriskostas 10 лет назад

nice illusion!!

@BenjiRevel 13 лет назад

Qi best programme ever made.

@kerezuke 13 лет назад

All I have to say is Wow.

@dunbar9finger 12 лет назад

If the light was from above you'd be able to see the difference between the top of the object being lit when convex, or shadowed when concave, which is a clue your brain will use to decide, since it's used to seeing light from above more than light from below. But they helped make the illusion stronger by lighting it from the side. If the left of the face is bright and the right of the face is dark, that could be convex+light from left, or concave+light from right and it would look the same.

@TurtleMC1993 2 года назад

1st saw Richard Hawkins do this on his "waking up in the universe" series from the early 90s. Theyre all up on RU-vid now!

@timoback3000 13 лет назад

Pretty cool

@yorkchiman 13 лет назад

@fxcw85, i maybe, but look at it..when the face is poking out, you see the face turning from left to right...when its inside its turning from right to left

@IoEstasCedonta 11 лет назад

What's really strange is that, at least at 4:30 in the morning, it looks like it actually begins to spin in the opposite direction.

@MrBebopChamploo 13 лет назад

@MrBebopChamploo AHA! I just remembered! He plays a chef on Bones that Booth talks to sometimes!

@GrumpyFarmerBill 13 лет назад

It's nice that sxephil acknowlages the existence of Qi

@RyanAcidhedzMurphy 12 лет назад

@willman2k8 It's the shadow from the edge of the mask falling inside, which forms the same contours

I saw the trick with the queen's face 17 years ago on the BBC! I've been performing it with various currencies ever since, to very appreciative audiences! :D I particularly recommend Abe Lincoln on the 5 dollar bill. :)

@ameann Год назад

Roughly the same forme. About 20 years ago I used to pull that trick out all the time. I had actually forgotten about it until today. Doesn’t work with credit cards and wireless payments 😂.

@SiliconBong 11 лет назад

Absolutely true there chameleonclone. Spent some years with a young man who was autistic. You would have to tell him how you felt, because he had no way of 'reading' your face.
