According this article, the company Morphsuits has introduced a costume that renders the wearer nearly invisible.
And just because a headline claims that the article is not an April fools joke, you believe it? http://www.livescience.com/44496-real-life-invisibility-suit-created.html
Isn't it kinda against the rules to say "It's no April Fools prank" in front of your April Fools prank? I highly doubt that anything like a cloaking device would be announced publicly before it's in actual use. It's too much of a military advantage to just spout stuff like that out.
Yes, but apparently it was the Morphsuit company pulling the prank, and the journalist who wrote the first article fell for it. And yes, that "No Aprils Fools" in the headline suckered me.
