LED Graffiti Magnets: For Those Times You Want To Make A Glowing Impression

There has been a time in everyone’s life when you have walked by a car and it has been totally filthy, prompting you to quickly write WASH ME on the back window, causing your finger to be covered in dirt. You no longer have to have a dirty finger. This set of 20 LEDs (red, blue, green, orange and rainbow cycling).This set of 20 different LEDs each has a battery and a magnet attached. All you do is pull the tab to activate, then toss them on any metal surface and whoila, they stick, leaving your message for all to see. Now everyone can be a digital prankster. Boy how times have changed.  [$9.99 at thinkgeek]
