Toxic Playgrounds?

Apparently, in Osceola County, Florida, three teens were arrested in connection with a fire that they ignited. When I read that, my initial response was that although it could have been very serious, it was garden-variety teenage vandalism. But, what really scared me was the underlying story....the fumes were toxic. Not just "make-you-sick-and-throw-up" toxic, but toxic to the extreme.

Read this:

"One whiff of that could actually send you into euphoria and possibly just kill you on the spot," fire investigator Detective Juan Bailey said. "It is that toxic."

Now, somebody please tell me --

WHY ARE WE BUILDING PLAYGROUNDS OUT OF THIS STUFF????
