Here are the latest rules for air passengers from the Department of Homeland Security:

No liquids or gels are permitted to enter the sterile area through the screening checkpoint or be in accessible property or on one’s person except:

  • Baby formula, breast milk, or juice if a baby or small child is traveling
  • Prescription medicine with a name that matches the passenger’s ticket
  • Insulin and essential other non-prescription medicines

Examples of liquids and gels included in these security measures include:

  • Beverages
  • Shampoo
  • Suntan
  • Lotion
  • Creams
  • Toothpaste
  • Hair Gel
  • Other items of similar consistency

Also, you will not be allowed to bring any liquids or gels purchased after passing through the security checkpoint onboard the aircraft.

Um, I’ve got an alternative idea for a liquid that should not be permitted into the passenger cabin of a U.S. aircraft: The brain matter of anyone hailing from or tracing ancestry to a country that sponsors terrorists or terrorism. We can start with Pakistan, homeland of the “British citizens” involved in today’s nastiness. Wouldn’t that be peferable to snagging Grandma’s toothpaste? She?s already gotta walk barefoot through the security gates and possibly have her brassiere frisked as well.
