This can only be used for evil.

It would be used for warfare, no doubt. Start inventing flying cars instead!


Which obviously wouldn't be used for warfare. Aerial warfare is clearly impossible.

People have already invented flying cars. It's not a practical concept. Even if someone invented a radical new form of engine that made it technologically practical, it still wouldn't be practical. The death toll would be far too high. Look at how many car accidents there are and then bear in mind that even a minor collision between two planes is extremely likely to result in them both crashing. "Fender bender, no injuries and a hundred to fix" would become "two vehicles destroyed, no survivors from either, several people killed on the ground and tens of thousands worth of damage done on the ground".

So... it's an Cloaking Device that relies on the enemy only looking at you through a special pair of binoculars you gave him? And if he doesn't use them, he can still see you??

You can hide something on the seabed, such as a submarine... ive got a better idea, why dont you get the submarine UNDER the seabed?

Not only can I see this uni from my house, I kinda know someone who's working on this. When I was first told I thought they were making it up.

Best I can tell, it's just refraction from a calcite crystal. I've been demonstrating this to geology undergrads for a decade now, to much ooohs and aaaahs from students, as I made a penny disappear. And this phenomenon has been known for centuries before that.

Sure, you're "invisible". As long as the observer doesn't take a step to the right or left. You'll forgive me if I don't hold the phone.

It looks like it's just a Polaroid lens that blocks off light rays, not really invisibility...Sure it would be invisible at night, when it could turn black from receiving no light and blend in with the dark. But otherwise, it just goes from being see through to be solid. Not invisible.


It's a very bad video that doesn't show what's actually happening. I thought the same as you, so I looked into it a bit more.

What the crystal does, in essence, is refract light around itself in such a way that light exits the crystal directly opposite where it enters, travelling in the same direction as it was when it entered the crystal.

The result is that when you look at it you see what is behind the crystal. You don't see the crystal and you don't see what is inside the crystal - that is the thing that is invisible. Under certain conditions in a lab, anyway.

@ ryan99: No it's not, it is a crystalline lens that allows the light travelling through it to refract (bend) around the object therefore the light does not hit the object it just travels around it causing it to appear ivisible. I read about this whilst doing my dissertation, done a similar(ish) thing but with sound

lets see where they go with this, it could be quite an impressive find.

no there is that pen thing behind it. we have actually talked about it in physics class. the crystal bends the light around the object. our prof explained it very well and the whole concept and how it works is very fascinating actually :)

So, still early days. Get back to us when you're a little more spectacular. Carry on.

I dunno. I think invisibility is something we should leave alone. A lot of privacy intrusions, more so than what we have now. Spying would be even easier too. Really is a sharp double edged sword.

I just saw the words " invisibility " and " cloak". Harry potter just came to mind.

But the crystal itself turns invisible. Not the things behind or inside of it. I guess if you made an airplane out of this it will confuse the enemy, but they'll still see you.
