I wonder if someone could take advantage of the super-absorbent gel "crystals" inside modern disposable diapers and use it to soak up their explosive liquid? Surely there is a way to do this without rendering the explosive inert (nitroglycerine might even be stabilized thereby).

And the diapers on the baby won't get ETD swabbed under most circumstances.

Bet the TSA hasn't thought of THAT one, either.
