But thanks to genius scientists in California, our dreams of sneaking around unnoticed could finally come true. Well, in the very distant future at least.
Researchers have developed a material that can make objects disappear.
At the moment, it's only tiny objects of microscopic proportions – but the technology could be used on a bigger scale in the future.
Magically, the material is made from gold nanoantenna blocks that alter waves of light.
The scientists told The Sun: "This is the first time a 3D object has been cloaked from visible light."
Now if they could just invent a marauder's map and time-turner, we'd be sorted.
