Group Description

Plastic Amazon #117

"Plastic can cover many synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity."

"Our parent catfish are kept in a 20-gallon high aquarium where we try to replicate the spring rainy season spawning conditions of the aldofoi's home waters, the tributaries of the upper Rio Negro in Brazil. The tank has several inches of gravel, a piece of driftwood, two plastic Amazon sword plants, a submersible heater, an air stone, a Penguin 550 power head, and a Millennium 3000 double filter. The water level is maintained at four to five inches below the tank top so that the two filter outputs create twin waterfalls, lots of bubbles and movement. The power head provides horizontal current and as far as the fish are concerned a river. Water depth is about eight inches. The temperature is kept at slightly above 70 degrees because the spring rains that help spark spawning in the Rio Negro cool the water."

"As she's gone from the Young Woman Who Could to the Woman Who Has, Ani DiFranco has explored more than her share of musical styles, all the while remaining true to her core. Even during her most extreme departures, you could hear the sound of the early albums coming through. On Little Plastic Castle, an album on which people are credited for adding pontifications, incantations, and an "evil machine" to songs, you could--for the first time--hear an almost completely new artist."

Types of plastic: PTFE, PVC, Teflon, uPVC, vinyl - Try Five.
