The Ingenuity of American Soldiers

I love human ingenuity. In a Newsday.com article it talks about American troops in Iraq using Silly String to detect trip wires. The troops spray the Silly String in a room. If it falls completely on the floor, there are no trip wires in the room otherwise there is. That's just plain clever! That is the very definition of ingenuity: thinking of ways to use an object for different purposes, not just its primary purpose.
