Scientists Make Cloak That Hides Things!

It has been the Holy Grail of scientists for centuries. Researchers announced they have built an 'invisibility cloak' that can hide everyday objects by splitting light.The 'cloak', which is actually a lump of calcite crystal, can make objects like pins and paper clips disappear from sight. Scientists have previously only been able to cloak microscopic objects, but a new study has taken a giant step forward by making items thousands of times bigger turn invisible.

Physicists from the University of Birmingham and colleagues from Imperial College, London, and Technical University of Denmark, said using the natural crystal enabled them to hide bigger objects than other researchers. The team from the university's school of physics and astronomy, glued two triangular pieces of calcite together, placed on a mirror.

The light enters the calcite and splits into two rays of different polarisations travelling at different speeds and in different directions. Although the cloak itself is visible, it hides objects placed underneath it. The researchers said the size of the cloaking area was not limited by the technology available but the size of the crystal and their experiments might pave the way to more devices which can hide much larger objects.

Thanks to Harry Potter, this could be a reality soon!
