Here are Todays Amazing Extremely Durable Deals!
Far more svelte than its lengthy product name, the Cyber-shot DSC-TX200V is Sony's new point-and-shoot flagship, packing an 18.2 megapixel Exmor R CMOS sensor, 26mm 5x optical zoom lens, 1080/60p video capture and a 3.3-inch Xtra Fine TruBlack OLED touchscreen. Sony claims that the cam's BIONZ processor can help it capture stills and video with extremely low noise, and an improved focusing system can deliver speeds of about 0.13 seconds in daylight and 0.25 seconds in lower-light conditions. Its reflective durable housing enables waterproof shooting down to 16 feet, and can protect the camera from dust and freezing temperatures of 14 degrees Fahrenheit.
If price is more important to you than an ultra-thin design and top-of-the- line spec list, then the DSC-WX70 and DSC-WX50 might be of interest. Both cameras include 16.2 megapixel Exmor R CMOS sensors, 25mm 5x optical zoom lenses, 12 megapixel stills during video capture, and 1080/60i HD shooting. There are nine "Picture Effects" options, adopted from the NEX series and also found on the TX200V. Both the WX50 and WX70 have a nearly identical list of features, though the first model includes a 2.7-inch display, compared to a 3-inch touchscreen on the ...

How do you make glass naturally?
How do you make glass using the elements air, water, and fire? Or, some other very solid clear substance that's extremely durable? So, for example..... if you were to have a hole in the ground about 15 feet deep, how would you fill it completely with clear thick solid glass? Would you fill the entire thing with sand,and heat it up? (don't worry about how to heat it)
Glass is often made by nothing more than natural elements.
Obsidian is volcanic glass and can be found in the USA in California with a composition of 75SiO2-13.5Al2O3-1.6Feo/Fe2O3-1.4CaO-4.3Na2O-4.5K20-0.7MnO(wt%)
Fulgarites are glass created from lightning strikes. Tektites are made at the bottom of the ocean (at hot spots) Diapletic glass is made from the heat of meteor impacts
Glass is made when a glassformer (silica, boron, vanadium...) is heated to a liquid and rapidly cooled before the atoms can arrange themselves in a regular, crystalline way. So all you really need is some sand, a lot of heat and then let it cool.
It will reduce the melting temperature if you add a flux to the glassformer, Sodium works well when mixed with sand to make glass.
