Welcome to the world of...
It's not going to actually fool everyone, but a China-Singapore partnership has demonstrated an “invisibility cloak” that works with natural light. While still pretty crude, the demonstration beats prior work in one key characteristic: it doesn't need polarised light (or microwaves) as previous cloaking demonstrations have …
"INVIZIBELZ LOLCATZ!" that look like they are about to take a shit.

Phew - looks like the cat is alive.
The first video looks like it could be a picture stuck to the back of the glass.
The second looks like the box is a synchronised video screen, thus it looks a slightly different colour.
Just looks like the effect you get with Transparent Desktop (littletinbox.co.uk)
While it does look fake, it'd be quite difficult to get teams at four universities to work together on a fraud like that.
Except with the goldfish you can see the shadow of the stirrer thing move in the first video. Still, until we get verification, I'm a bit doubtful...
How does the glass 'know' to hide the fish/cat, but allow the flowers to show?
Because the fish/cat are inside the "cloak" whereas the flowers are not. I suspect that you are thinking that it's like this from above:
--------- <- "cloak"
When in fact it's like this:
| Fish |
i.e. the fish/cat is surrounded by the cloaking material.
@Alex - that makes sense. Thanks.
Weed/flowers is behind the "cloak", fish/cat is inside it.
A fake would look much better!
So it must be mirrors.
..about the fish but everyone knows that all cats can make themselves invisible at will.
Cats can also make fish invisible.
Have an upvote, that made me chuckle!
"Cats can also make fish invisible"
They are probably even quicker at making themselves invisible if they've made a fish invisible
I can do that with sardines.
Help the Massive Chinese PLA develop invisibility so no-one will notice when the invade Taiwan, India, Vietnam, Korea, Cambodia etc.
What is that Chinese Take-away van doing parked outside? I dont remember ordering any Ch
sounds like a recipe to use mirrors. It'll only work from a static point of view, but their demonstration videos show nothing beyond that.
Please tell me that I am wrong!
It's all in the paper, and not complicated. They also describe the limitations.
You are wrong.
I hope you feel better now.
By leaving it alone with the cat... amitite?

The fish will still bite the hook if I know where to find 'em, even if I can't see 'em. And I can send the dawgs after the fscking ground squirrels, even if there is tall grass to hide in.
Ability to use tools is all very well and good ... knowing which tool to use, and when, is far more important.
This toy is just that ...a lab toy with zero practical use.
Common practical uses for lab toys with "zero practical use" are as a demonstrations, proof-of-concept, or as educational equipment. I think this can function as all three.
>zero practical use.
didn't they say the same about LASERs?
Jake, like Eadon, you never fail to perform to your stereotype.
Well done. Consistency is good, even if the consistency is bad.
I dunno, I was expecting jake to come on and tell us this is nothing new, he made the first ones of these back in the 80s and can make his ranch disappear.
Heh - Don't mind Jake. He's not used to being called out on his idiotic pronouncements -spent his life as small fish in a tiny pond I wager - He hasn't quite gotten used to the big bad innanet yet.
The practical use is fscking up Google's Street View photography.
I suspect they have.
Pepper's Ghost comes to mind.
so, silly question, why can't the wand be seen and the plants can be seen? I suspect the invisibility shield is actually a photograph. An easy demo to make for anyone with a camera, photo printer and a you tube account. I look forward to a plethora of invisible fauna with visible flora.
If you experiment with cats and goldfish, of course the fish will disappear.

This is bullshit. You can tell because the cat went exactly where it was supposed to and took a seat. Cats never do what you want them to do.
if my cat is anything to go by then the simple act of paying more attention to any given object than the cat is likely to cause the cat to go and sit there. Makes wrapping christmas presents fun.
Ah, but the object appears to be a box, which as you know a cat can't resist.
It's true, any box will put a cat right where you want it.
Every cat in every box ever:
Lame trick I think, hiding stuff behind a flash player "Error #2124" ... doesn't fool me for a minute.
Agreed*. Didn't Flash die already?
* I had Error#2036 myself
... whilst its obviously setting up to take a poo! LOOK!
Funny, my wife said the same thing when she saw the Video. Her exact words were "Why am I watching a video of a cat getting ready to poop?"
Didn't they do this on Top Gear?
And in what way is anything in those videos any different than what you can see most nights in Vegas at countless shows?
Other than not being nearly as good as watching Penn and Teller - I swear that Teller could palm a running chainsaw.
There's another link between those videos and Penn and Teller, and that is
