Nanotube Paint Blocks Cell Phones on Demand
Kozar_The_Malignant writes "Newsday is reporting on a new nanotube paint that is able to block cell phone signals on demand. The nanotubes are filled with copper, suspended in paint, and can be applied to the walls and ceiling of places such as concert halls, churches, and classrooms."
Run outside the classroom or concert hall.
Try this if there is another Colubine or a fire or you're locked somewhere within and can not get out. What if it's YOU who's having the heart attack and you're alone? Do you really think you're going to "run outside"?
