Egg Balancing Act on the Edge of a Knife
Joseph Janney Steinmetz was a world-renowned commercial photographer whose images appeared in such publications as the Saturday Evening Post, Life, Look, Time, Holiday, Collier's, and Town & Country. His work has been referred to as "an American social history," which documented diverse scenes of American life from affluent northeasterners to middle-class Floridians. Steinmetz moved from Philadelphia, Pennsylvania to Sarasota, Florida in 1941.

Perpetual Printer- Reuse Papersheets
Printing has come a long way since the computer landed on the desktop. First, there were daisy-wheel printers, then dot-matrix printers, then inkjet and laser printers. The problem with all of these output devices, of course, is that they require paper -- lots of it -- and expensive consumables, like toner. Why can't someone invent an inkless, tonerless printer that allows the operator to reuse paper?
As it turns out, this isn't a new idea. Xerox has been working with so-called electronic paper since the 1970s. Its most promising solution is a type of paper called "Gyricon." A Gyricon sheet is a thin layer of transparent plastic containing millions of small oil-filled cavities. A two-colored bead is free to rotate inside each cavity. When a printer applies a voltage to the surface of the sheet, the beads rotate to present one colored side to the viewer, offering the ability to create text or pictures. The images will remain on the paper until it's fed through the printer once again.
A Japanese company, Sanwa Newtec, is offering its version of inkless, tonerless and rewritable printing technology. Its product is called the PrePeat rewritable printer, which, like the Xerox solution, requires plastic paper. But PrePeat uses a different technique to produce an image. Each sheet of paper comes embedded with leuco dyes, which change color with temperature -- colored when cool and clear when hot. The PrePeat printer, then, heats and cools the paper to first erase an image and then create a new image in its place. According to the company, a single sheet of paper can be reused 1,000 times before it needs to be replaced.
What's the catch? A single PrePeat printer costs almost $6,000, while a pack of 1,000 sheets of paper costs more than $3,300. If you're running a printing-intensive business, you might be able to recoup your investment over time. But the average PC user likely won't be willing to shell out that kind of money to replace a standard printer [source: Miller].
The Thorny Dragon
The Thorny Dragon is an Australian lizard that resides mostly in the desert. They are also known as the mountain devil, the thorny lizard, or the moloch.This lizard is covered in sharp spikes, and it uses these to frighten away predators. The crazy thing about these lizards is that they can live for up to 20 years - that's a lot more than most lizards!
The Blue Parrotfish
Smile for the camera! This comical looking fish is known as a Blue Parrotfish and they average 30-75 cm in length. Some can grow up to 1.2m though - crazy! There is no other species of fish that contains such a stunning uniform blue color across the whole species. The Blue Parrotfish spends a whopping 80% of its time looking for food.
Blind Snake
This snake has a few different names, all of which refer to it's unusual likeness to the male member. This animal has no eyes and it is actually called an Atretochoana Eiselti. It is presumed to be an aquatic, almost eel-like animal due to its fleshy dorsal fin on the body. Found in the Amazon River, this species was only rediscovered in 2011!
The Panda Ant
Ants can be pretty annoying, but add some fur and panda print, and you've got yourself an adorable insect! But did you know that, despite the name, this is actually a species of wasp, not ant? Crazy! Found in Chile, the wingless females resemble large, hairy ants - hence the name. These insects might look cute, but they've got one nasty sting.
