Invisibility Clock - like to be a Hollow man ?

Daily scientist do something new, now they get the secret of invisibility clock and have come with a workable design for an invisibility clock, same type of clock which you have seen in Harry Potter's movie, if not than watch and get an idea that what we are talking about.
Last year physicist figured out the very complex mathematical equations by which they can make things invisible by bending the light around them.
At Purdue University, Indiana, USA , a group of engineers have used those calculations to make a device which may be one day ,able them to disappear a giants like aeroplanes.
Everything have good and bad effects , for army personal its fine, they can hide their self from night vision goggles and can deceive laser lights, which is used to illuminate surface to see things, but if the same device crooks got than what happened , they can use it very negatively, hummm ! let me think what i can do with this, mmmm , if i got this device the first thing which i will do, i will not tell you , now i stop writing and start thinking about the negative use of it, so its better to not think about it, it will lead us to bad things. So its better that only government can have access to these type of things , i know governments also used this for spying to other countries, but what we can do.
