Who can forget last summer’s dumpster swimming pool in the Gowanus. That was created by David Bell, a local developer. This year he’s creating something called  “Glassphemyl,” an experiment in recylcing.

The installation set in a private space along the Gowanus Canal in Brooklyn, is a 20-foot-by-30-foot clear box, with high walls made of steel and bulletproof glass.

People will stand on a high platform at one end of the box and a low platform on the other so that they’ll be able to toss glass bottles into the box—and at each other though no once can get hurt thanks to the way its designed.

Sounds fun.

And there’s more: as the bottle smash,  lights flash, and no one is harmed.
