  3. An amazing science trick with smoke and a flame. Try it at home. Video:
  4. Unbelievably Strong Glass - New Revolution in making thin Glass This is a new type of glass which will be manufactured in the future. It will replace ordinary glass in the near future. It will also be used by mobile phone manufacturers. This type of glass is the strongest glass in the world. It is ten times stronger than ordinary glass.It is resistant to scratching and hard impacts, which is presented in the test. In the test, we will use two steel balls and two glasses for shattering. The first glass is made of the new type of glass, while the second one is made of ordinary glass that is currently used.
  5. Interesting reaction coke and milk The reaction of phosphoric acid (V) to proteins in the milk - they are cut and causes a precipitate The reaction of phosphoric acid with calcium contained in milk gives rise to a precipitate 3Ca + 2H3PO4 ///\\\ Ca3(PO4)2 + 3H2 Video: Source: http://cocacola-and-milk.blogspot.com/ It is a reaction of the Phosphoric Acid contained in the coca cola to the milk. Phosphoric Acid molecules attach to the milk giving them more density and separate out while the remaining liquid that makes up the milk and cocoa cola now being lighter floats on top. The solid matter is basically milk that has been curdled by the addition of the more acidic soda. Both items are acidic but coca-cola more so. In general, coca-cola has a pH of anywhere from 2.5-4.5 because of the Phosphoric Acid content where milk has a normal pH around 6.7 (almost neutral, milk that is in the base range is usually mastitic). There are some studies to suggest that because of the high Phosphoric Acid content in most soft drinks that they can help to increase the likelihood that a person will develop Osteoporosis if they aren't getting enough Calcium in their diet. Coca-cola makes an excellent household cleaner - it can be used to take tarnish off of pennies and I've used it to degrease car engines. I will not drink any soft drinks.
