Anti-WiFi Paint

     Don't you just love it when you're on vacation, or you don't have internet in your house, and a neighbor just so happens to have a usable WiFi network you can leech off of? I mean, come on, who doesn't like free internet?! Nobody!

     Well, unfortunately, the days of free internet may well be over with the invention of WiFi blocking paint. Oh, you read that right, paint that blocks WiFi signals. So, in theory, someone could paint their house with this, and your free internet would be gone forever!!!

     In all seriousness, for large scale corporations this could be quite useful for security purposes. Being able to block any other parties from connecting to their networks could prevent intrusion from malevolent hackers, or just people who could steal away their bandwidth. And they could do this without the need for expensive hardware or cumbersome software.

     So, for all you internet stealers out there, you might need to start paying for your own internet...

     Yes, that's right, internet does cost money.
