Ever since I was young, my cousin Chris and I were like two lab rats when we were left about our business at family parties. I still remember today the red work bench we would sit on in the storage room with a roll of tin foil, tape, rubber bands, and various other random supplies. About 15 years later, Chris and I are no different. Just the other day he sent me an article from the website Physorg.com. Physorg is basically a site dedicated to any form of science, be it natural or physical, and has all the hot news on the up and coming. Chris sent me an article titled, "Spray on liquid glass." Naturally I was extremely interested, clicked to the site and began to read. Spray on Natural glass constitutes the molecular build up of Silicon Dioxide. It isn't exactly what you are picturing, which is probably a sticky layer of thick plastic looking junk that would make a mess and have no real practical application aside from what you would find on an infomercial. Spray on glass is totally invisible, partly due to the fact that it is only 100 nanometers thick when one layer is sprayed. That is about 15-30 molecules stacked high, i.e. extremely freaking small. Anyway, this stuff can be used for just about anything you can imagine. Its like an invisible impenetrable shield. It is an extremely flexible, breathable, non toxic, water proof substance. Applications include: spraying on grape vines to protect them from fungus, spraying on plant seeds causing them to germinate extremely quickly, spraying counter tops and effectively halting the spread of bacteria due to properties that make it difficult for bacteria to multiply, spraying on a car to make an extremely protective paint job, or lightly spraying silk cloth protecting it from red wine stains completely. When sprayed on a sterile surface, the surface remained sterile without cleaning for 4 months, which is apparently much longer than usual. In a restaurant setting where you would have to bleach down a counter top after slicing meat, you would only need a wet hot washcloth to wipe the counter top down with. Spray on glass can be used in just about every possible setting. It was very recently invented and is starting out in the UK and Germany. It was invented in Turkey and patented by a German family who own a company called Nanopool. I know I've ranted on for a while but this is going to be a very big thing in a short time to come, it will probably be used on everything tangible. Check it out at www.physorg.com, even if you dont care about the spray on glass, I am absolutely positive you will find something here that you find interesting.
