Scan your friends for their level of nerdiness. Fun trick to play on your friends. You secretly control Nerd-Alert to go off when you point it at your friends. It pings like a radar as you scan your friends and you choose when the alarm sounds indicating the presence of a nerd. It always gets a laugh. The trick is so simple, but yet very difficult to detect how you make the scanner jump from low to high as you point it from friend to friend. Your friends will inevitably want to try it for themselves (thinking they know how to set it off) just to try it and not be able to figure out how you make it work. The motion to make it work is so simple and subtle it is virtually undetectable.

*** Lie-Detector, Babe-Alert & Hunk-Alert are also available from iCOOLgeeks.

Features:
- Fun practical Joke to play on friends
- Super easy to learn the trick
- Difficult for people to detect how you do it
- Makes them laugh every time
- Great bar trick

Give it a try! You'll be surprised how much people laugh at it and want to try it for themselves.
