(10/16/07) TRENTON (AP) - About 80,000 cans of Silly String are on their way from a Deptford warehouse to Iraq. Marcelle Shriver collected the cans after her son, who is stationed in Iraq, told her soldiers use it to detect trip wires on bombs. But after an initial shipment, the Stratford woman struggled to find a way to send the thousands of cans. The aerosol product is considered a hazardous material, meaning only certain companies can ship it. Thom Campbell of Capacity LLC heard about Shriver's struggles and decided to help. The thousands of cans are boxed and addressed to individual servicemen and servicewomen. They'll be shipped to the United States Postal Service for delivery with other letters and packages.
