Scientists develop material so dark you can't see it

As a science teacher, I've always enjoyed teaching students how dark true black really is. I take a large cardboard box, poke a small hole in the middle of it, and have students hold other "black" objects next to the hole. Students are pretty consistently amazed to see the difference, if they have never noticed the phenomenon before on their own.

I would love to see this material in person.

Perhaps it would be pointless, but I'd still like to see a photo.

I wondered that, would you be able to convey it digitally? I have seriously no idea!

Funny. I guess it would just be 0x000000;

In the 8-black ball example, you guess the form of the object because you can see the shadows and reflections because it's not true 100% black.

It would be nice to see a similar object with the new almost perfect black cover, and see that it looks like a hole because you don't have the shadows and reflections.

In the digital version, you can't see that it's perfect black, but can see that the tone is constant.

Best inane comment from the article's comments section:

"Its dark black then."
