Yay! I did a search and actually found a post (I think). This Yahoo story is out of date, so I guess that makes it worthy of a bump with a more permanent link:

Quote

Silly String and similar products have long been used by American and British forces to detect tripwires for explosive booby traps. To use it in this manner, the soldier stands in the doorway and sprays the material over the suspect area. If the string falls to the ground there are no tripwires. However, if there is a tripwire, the string will be suspended in the air without pulling the wire. [4] [5] [6] [7] As of 2006 it is being used by U.S. troops in Iraq for this purpose.
