1. There is a myth that states that hot water will freeze faster than cold water, due to an effect called the Mpemba effect. One of the several possible explanations for this effect involves evaporation: if you start with extremely hot water, quite a lot of it will evaporate (and a smaller quantity of water will freeze faster than a larger quantity). And so, according to chemists, it is possible and not a myth.
2. Coca cola can remove gum from hair. The chemicals found in Coca-Cola will loosen the gum and make it looser and easier to pull out.
3. Some websites say that Coca-cola can remove rust because of the phosporic acid in the coke. However, others say that Coca-cola causes nails to rust as rust is caused by oxygen combining with the metal, in this case iron and steel. The acid in the coca-cola strip off contaminants and increase the speed at which this process takes place. Acid also has oxygen in it and when it meets up with various other items it makes more oxygen available for the process. Apparently, oil protects the nails by preventing oxygen from getting to the metal.
