(December 7, 2006)--It's not some high-tech gizmo from the Pentagon.

In fact, you're more likely to see it on a playground than in a war zone.

But it turns out Silly String has a serious purpose in Iraq.

A New Jersey woman found this out from her soldier son.

Before entering buildings, troops will shoot the plastic goo, which usually travels up to 12 feet.

If it falls the ground, they know there are no trip wires around bombs.

The wires are nearly invisible.

Marcelle Shriver sent her son a couple of cans of it, and enlisted some church help in starting a Silly String drive.

One thing led to another and she now has a thousand cans in her garage, waiting for a pilot who's agreeing to fly them to Kuwait.

From there, they'll be transported to Iraq.

The makers of Silly String donated some, and say they're pleased to be part of the troops' innovation.
