Here is my next invention proposal...
I want someone to invent a cell phone scrambling device I can use in my classroom where when I choose, I activate the device and every cell phone in the room becomes scrambled rendering it unusable. This would make my life much easier. I feel like I'm constantly policing teenage texters. I suppose I could be harsher on the kids, but then again they are just kids. Anyway, lets name the device cellscramble.
Of course, there would have to be a way to exclude my cell phone from this whole thing... I guess that would be the tricky part.
Make it happen people.
