Seems like it is just this week I've read about the TSA waving some kind of magic paper over travelers liquids.

What is up with that? Is it like my magic rock, or is there something about it?

It wouldn't surprise me to discover that it was simply psychological theater like the rest of their antics. Similar to the earlier, now discontinued, practice of ordering everyone to "freeze" for some limited period of time, presumably hoping to frighten some bad guy into running. . .

Keep piling hay onto the stack, TSA.
