Still think that something other than a mere plane crash brought down the World Trade Center towers? According to a Norwegian materials expert, you may be right. Just ... you know ... not in the way most Truthers probably expect.
"Christian Simensen thinks the Twin Towers were ultimately felled by a thermite reaction.
'If my theory is correct, tonnes of aluminium ran down through the towers, where the smelt came into contact with a few hundred litres of water," Christian Simensen, a scientist at SINTEF, an independent technology research institute based in Norway, said in a statement released Wednesday.
'From other disasters and experiments carried out by the aluminium industry, we know that reactions of this sort lead to violent explosions."
Given the quantities of the molten metal involved, the blasts would have been powerful enough to blow out an entire section of each building, he said. This, in turn, would lead to the top section of each tower to fall down on the sections below.
The sheer weight of the top floors would be enough to crush the lower part of the building like a house of card, he said."

Very good theory and all but it still doesn't explain why the owner of the WTC building said "We had to bring them down"
Generally, thermite is made by mixing Iron Oxide and Aluminum powder and igniting it at very high temperatures (a few thousand degrees). The reaction releases so much energy, molten Iron metal is produced as one of the products.
The two most common types of thermite are made using either Iron(III) Oxide, Fe2O3 (also known as Hematite), or using Iron(II, III) Oxide, Fe3O4 (also known as Magnetite). The Iron Oxide is mixed with finely powdered Aluminum metal. When the thermite reacts, liquid Iron metal and Aluminum Oxide, Al2O3, is produced as a result.

If you had an open flame near it would make a nice explosion.
Thermite is not easy to ignite. Thermite has a very high activation energy required to start the reaction. The two most common ways to ignite thermite are:
Magnesium Ribbon (Mg)
Magnesium metal burns in an Oxygen environment (air) in a very bright, exothermic reaction. Magnesium ribbon can burn at several thousand degrees easily igniting thermite. The Magnesium ribbon is useful as it acts like a fuse, calmly burning, allowing a short delay between when the ribbon is lit and when the thermite begins to react.
Other forms of Magnesium metal can be substituted for Magnesium ribbon such as metal turnings, powders, or even common sparkers which contain Magnesium.
Potassium Permanganate (KMnO4) + Glycerin
An alternative to using Magnesium ribbon is to use the heat given off by the reaction between Potassium Permanganate and glycerin. Potassium Permanganate is an extremely powerful Oxidizer which spontaneously ignites after coming in contact with glycerin.
After adding a few drops of glycerin to Potassium Permanganate powder and a short delay, a violent exothermic oxidation reaction occurs which will ignite a thermite mixture.
It is important to mix the thermite ingredients thoroughly in order to create a homogeneous mixture. Unless the thermite is sufficiently mixed, it may be difficult to ignite or sustain the thermite reaction.
Ignition
The ignition temperature of thermite is extremely high. Therefore, traditional ignition methods like fuse, matches, and electrical igniters do not work. There are several ways to safely light a thermite mixture, the most common being:

This is not a new theory by a long shot.
The contents have to be very finely ground and mixed in the correct amounts.
Badly mixed thermite will not react very well, if at all.
