Now after some years a scientist found out that there might also be a different reason why the world trade center exploded. The airplane was made out of aluminium and that aluminium melted when it crashed fastly into the towers. The melted aluminium combined with water that came from somewhere where the sprinklers where. Of course that made an extra explosion and that is one reason why the World Trade Center collapsed. As everybody knows can some elements be very reactive with water or other elements. In this case they would only need one drip of aluminum to destroy almost one floor. In the article they say that tons of the molten aluminium ran down from the towers. There was the whole water system for the sprinklers with tons of water too. That means that it could be possible not only that the explosion destroy some of the building. It could have destroy the whole building. So it collapsed because of an explosion. Before they came up with that idea they thought the the World Trade Towers fell because of the steel structure. The steel heated up and then it was not stable any more. That's was the first theory why the Towers fell. They made an experiment after that to know how strong molten aluminium can be. They mixed 44 pounds of molten aluminium and they used 20 liters of water. Then they combined them. The result was a huge crater, which's diameter was 100 feet long. That is just crazy, if you think that 44 pounds are only 19 kilograms. What would happen if there are 30 kilograms instead of 19. That would not be funny.
