Hydrogel is mostly water, but strong as silicone rubber

You’re looking at a piece of hydrogel. It is 98% water by weight. It’s moldable, transparent, environmentally friendly, easily synthesized and (get this) if it’s cut it will heal itself. Its creator, Takuzo Aida at the University of Tokyo, has compared it to silicone rubber in terms of strength. And to make it, all you have to do is stir three ingredients into a bunch of water at room temperature. These are sodium polyacrylate, clay, and a special dendritic macromolecule Aida and co-workers call “G3 binder.”

158-lens camera

Built by Associate Professor Yojiro Ishino of the Nagoya Institute of Technology, this giant camera took six months to build and has reportedly been certified by the Guinness Book of World Records as the camera with the record-holding highest number of lenses. It’s about 3 inches high and 18.5 inches across, and was built to study flames by capturing them simultaneously from as many angles as possible. [via Neatorama]
