Glass Cube Sculpture for the Gowanus

According to the Daily News, the muck and black mayonnaise that is at the bottom of the canal could be used for a novel purpose: being superheated and turned into glass cubes. The cubes would then function as any glass brick structure, able to be used in a number of applications.

""You could construct an aquarium," Tsiamis said.

"It could become the basis for an art sculpture for the community. Maybe they want to build a monument to commemorate the cleanup of the canal."

The sludge, which is about 10 feet deep, is a mix of industrial metals, coal, tar, sewage and mud.

"That material is really black and nasty," Tsiamis said. "It's oozy like lava. ... It has the texture of mayonnaise.""

Sounds like the EPA's project manager is throwing a lot of black stuff at the canal walls, and seeing what sticks.
