9. Experiment There was made an experiment: The Coca-Cola’s impact to 2 cents coin and the origin of organic materials - nails. The methodology of the experiment is simple: the nails, as well as a coin are placed into separate containers with Coca Cola, Libelle Citrusmix drink and Lithuanian Just Cola Classic. Whereas the experiment is not scientific, we add drinks without measuring, because it does not make a big difference. The experiment will last some time. We will hold the experiment failed if the nails are in the jar and there are not visible effect on the two Lithuanian-cent coins and they could be used in circulation. The experiment will be held succeeded, if the nails melt and there we could see visible changes of two cent coins.

10. The results of the experiment 1. First day: The nails in the jar floated for some time on the surface of the drink, then they deposited to the bottom. The coins deposited immediately. 2. Second day: Nails are lying the same on the bottom of the jar. The coins took over the same colour as the drink. 3. Third day: Everything is the same as before. 4. Fourth day: Everything looks the same. It is very interesting, whether the coins will be soften or not? 5. Fifth day: There is nothing new, so we make the conclusion that the experiment will be failed. The coins that were in Just Coca has no brown-colored stripes. The coins that were in Coca Cola has brown stripes. It is obvious that these drinks have different concentration of dyes, which is bigger in Coca-Cola.

11. The results of the experiment 6. After a week: After a week the nails are not melted, metal coin as well. Only one visible difference between coins which are in Coca Cola and in Just Cola because there colours are different. The coin in Just Cola did not changed the colour, while the coin in Coca-Cola became brown. Thus, we make conclusion that Coca Cola from the USA has more bad materials. 7. After two weeks: In these photos we can see the difference between coins: Coca Cola: Just Cola: Coca Cola: Just Cola:

12. Conclusions Coca cola is a very dangerous drink. This drink has got a lot of materials that influence our organism so that we want to drink again after a very short time because we do not freshen up with this drink. The purpose of the producers of Coca Cola is not to give refreshment, but to make people, particularly children, to buy this drink again and again.
