This is very much a rumor right now, but there are a couple sources who have been pretty reliable in the past that seem aware of it to some level so I’m pushing it up into the “very likely” rumor category.  Apparently the TSA is no longer satisfied with simply banning an entire form of matter – liquids – from air travel.  Now they’re moving on to “things that can pour,” namely powders.  I don’t know much more than that in terms of whether it will be all powders, whether a small container inside the already bulging “freedom baggie” will be permitted or anything else particularly concrete, but it seems that something is coming down the pike in this regard.

The security theatre continues. 

More on this if or when something actually gets announced.
