"After months of frustration, a mother of a soldier in Iraq has found someone to ship about 80,000 cans of Silly String to the troops, who use the foamy substance to detect trip wires on bombs."
"Shriver's Silly String campaign began late last year after her son, Todd, a soldier in Ramadi slated to leave Iraq in November, asked his parents to send cans of the product. Soldiers can shoot the substance, which travels about 10-12 feet, across a room before entering. If it hangs in the air, that indicates a possible trip wire."
