Cloaking Device not just for Star Trek anymore

Fear not parents, these scientists are pretty far from developing a cloak like the one in the Harry Potter stories so the kids don’t have the means to score cookies without being seen. 
 
I caught the gist of this development on NPR but found more about it online through The Economist. I went with a link from the BBC here instead because they don’t archive theirs off in a couple weeks for only subscribers to access. 
 
Even if this invisibility technology only applies to the lower wavelengths and would be put on objects such as planes, it’s still cool to see they have figured out how to hypothetically extrpolate this visible light like we’ve seen in thePredator movies. 
 
The only downside will be the arguing over how invisibility really works versus the magic spell when we’re playing D&D.
