Welcome to the world of...
INVIZIBELZ LOLCATZ!
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 …
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:
Flowers
Fish
--------- <- "cloak"
Observer
When in fact it's like this:
Flowers
-----------
| Fish |
-----------
Observer
i.e. the fish/cat is surrounded by the cloaking material.
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.

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
BULLSHIT!
Would a functioning invisibility shield also work in the other direction, against incoming photons?
I'm just wondering if developments along these lines could be used to shield a target from the high-energy laser weapons being developed at the moment. If you can redistribute the photons then that kind of makes the enrgy weapon obsolete. Though I'm guessing the energy would need to be dissipated somewhere, so you'd either need heatsinks or batteries or another laser to just vent the energy somewhere else.. even back at the attacker.
Now if you could just get rid of the physical medium and generate an energy field which could manipulate photons in the same way as the glass shield.. boom! There's your Science Fiction energy shielding/Romulan cloaking device.. as a poster above me mentioned. :)
PS: This could solve world hunger.
The cat and the fish are put behind the shield.
The fish then enters a quantum state where it is both inside the cat's stomach, and not inside the cat's stomach *at the same time*.
The cat is happy, because it's eaten the fish.
The fish is still happy, because it's not been eaten.
Remove the shield. Replace the cat with another hungry cat and repeat the process.
Maybe this is how the loaves and fishes thing worked 2000 years ago?
