I think crushing the gypsum and making a slurry with a little water is a must. But you could probably melt the aluminum the way Prof. Jones did.... As for doing the test in a laboratory, that is also ok. The burning plastics, etc, are just to cover all the bases since the important thing is to reproduce the conditions in the WTC. However, from the simple chemistry point of view we are looking at the reaction:
2Al + 3CaSO4 -> Al2O3 + 3CaO + 3SO2, which appears to be exothermic, (but you may still need to heat the gypsum!?!)
8AL + 3CaSO4 -> 4Al2O3 + 3CaS, if aluminum is in excess,
but you may need a side reaction between water and aluminum, i.e. a reaction that generates hydrogen, to get the thing started, hence water may in fact be the key...
I really don't have all the answers................ Do you intend to do this test? Or do you know someone who could? Cheers, Frank
That's great! But, tell your friend to be carefull - these tests are potentially dangerous and I don't want to see anyone getting hurt. If the tests are done properly and nothing happens, I will stand corrected; but I am basing my predictions on articles that are in the literature for anyone to check out. Cheers, Frank

Great work, Jack! -- I’ll do this test, and probably next Monday…

voted you way above, jack. amazing.
in thermite, the metals are powderized, right? isn't this important to making the reaction work? would there be enough loose rust to make a signifigant reaction?

I'm also curiously awaiting prof Jones experiments setup on coming monday, Jack Tripper !
We did the experiments this afternoon, with photos (to come later) -- Here’s a brief summary:
Next we tested ideas of Greening (discussed in a paper on our website). This time I did two more tests:
1. Crushed gypsum (from drywall) mixed with crushed concrete and plastic pieces and placed on a very rusty steel channel thrown in to cover all the bases -- trying to reproduce conditions as might be found in the WTC. Greening’s idea is that molten aluminum from a plane might hit these materials and lead to violent reactions, culminating in Tower Collapses!
However, the experiment showed no violent or even visible reactions. The molten aluminum flowed around the materials with no obvious reactions at all.
2. The mix described above was repeated, and this time mixed as a slurry in water. Greening suggested that molten aluminum plus water might generate hydrogen, perhaps to get reactions started. And there could have been water in the WTC.
Again, the experiment showed no violent or even visible reactions, except that some steam was generated. No flame whatever in either experimental test. The molten aluminum flowed around the materials with no obvious reactions at all.
