Scientists are a step closer to creating a cloaking device after making an object visible to the naked eye disappear for the first time.
In the past, researchers have only been able to "cloak" microscopic objects using extremely complicated physics and so-called meta-materials made on a tiny scale.
But a new study at the University of Birmingham in the UK has taken a major step forward by making a paper clip invisible - an object thousands of times bigger than in previous experiments.

We should brainstorm as many uses for this as possible, I'm wondering what every day uses it could have
So they can make a paper clip invisible by placing calcite crystals over it? If the crystals are visible I'm not sure how great that is.

Unfortunately this implementation requires some thickness of material and the result is less than portable and inconspicuous.
Also, calcite has a hazy and milky appearance due to its microstructure and so the fact that it hides an object is overcome by the "cloak" being visible.
