Most people are familiar with welding metal, but it’s entirely possible to weld plastic. There are a surprising number of ways to weld plastic, but first you will need to identify what kind it is. The smell of burning plastic is a particularly effective diagnostic. This man is welding with hot air. Many instructional videos are made by companies whose products are featured in the video, like this somewhat surreal demonstration of speed tip welding. Perhaps the most low-tech method is with a soldering iron.

In the early 1950's, Monsanto Chemical Company, MIT and Disneyland collaborated their resources and creative brainpower to build "the house of 1986." Using 30,000 pounds of plastic (The building's structure, carpet, chairs, sinks, appliances and floors were all plastic. About $7,500 to $15,000 worth.), the Monsanto House of the Future* was opened to an excited public in June of 1957. It was closed in 1967 as ideas of the future were beginning to change. Let's take a quick tour, shall we?
*(Not to be confused with Xanadu Homes of Tomorrow.)

The Faces of War, a fascinating document of the prosthetic masks used to cover serious facial injuries from the battlefield. Before plastic surgery was widely practised and used to reconstruct the horrific facial injuries of the First World War soldiers, men with the most serious facial injured were often hidden away from society.

Men such as those recorded in watercolour, and in pastels (warning: some may find these images disturbing); patients of Harold Gillies, pioneer of facial reconstruction at Queen's Hospital, Sidcup, the wars major centre for facial reconstruction and plastic surgery.

Loes Modderman's Science Art
Beautiful microscopic art, often striking similar to some modern art. Dig the abstract crystal images: cholesterol, crystal landscapes, vitamin c is psychedelic. Explore the sands of the world! Bubbles are pretty, plastics rock, fluids are minimalist. (via)

Mold A Rama! Remember those plastic lions, tigers and gorillas? How about an Abraham Lincoln bust or locomotive? You remember those machines where you stuck a quarter in and watched as 250 degree plastic was pumped into a mold and then automotive antifreeze was hosed in to supposedly cool the mold before the animal was pushed into the compartment below for your waiting hands. Remember the burnt plastic smell? Those really hot to-the-touch animals that you wore down your parents until they gave you a quarter animals are not just simply things from your fading memory. Uh uh, new molds are being made even today. Not good enough you say? Then buy your very own vintage Mold A Rama for a mere $9,500!

Microscopic fragments of plastic are a "major pollutant", floating in the ocean, settling on seabeds, and washing up onshore - with unknown consequences for marine ecosystems, according to a new study. "We've found this microscopic plastic material at all of the sites we've examined," [lead researcher] Dr Richard C Thompson [of University of Plymouth, UK] said. "Interestingly, the abundance is reasonably consistent. So, it suggests to us that the problem is really quite ubiquitous."

Plastics! A new revolution in packaging, "By some measures, films made of metallocene-based polyethylenes can have two to three times the tensile strength, five times the impact strength, and twice the tear strength of a traditional polymer. That allows users to make much thinner films and parts, saving on everything from plastic resin to transport costs."

One word...Plastics. New techniques for restoring bones. Speaking of broken bones, is everyone else dreading the full media coverage of Ronald Reagan's slow liquefaction over the next several years.
