If the Factory Container is not clear, such as most shampoo bottles, the contents are not visible and could be replaced. Under 3 oz of mouthwash is allowed. "Do not overthink these guidelines". If I carry 2 oz of allowable mouthwash in a 2 oz Head and Shoulders shampoo bottle, is that OK?

Nowhere on http://www.tsa.gov/travelers/airtrav...ted-items.shtm can I find any reference to Original Factory labelled Containers ONLY. Like GG, many things that you only need a small amout of for a few day trip are easier to put a dab in a 2 x 2 inch ziploc, much lighter than carrying even a 2.99 oz tube.

The Official Approved "My Ziploc"™ picture at http://www.tsa.gov/press/happenings/..._guidance.shtm shows seven 2.99 ounce (under 3) continers Resting Comfortably™ in their quart baggie. My math says if I dumped the original contents and filled them all with water I would have 20.93 ounces of water. Yet I cannot bring a 16 ounce bottle of water.

To really show the lack of uniformity of the Partial Water Ban Rules v. 9/26 per v. 8/10:
At http://www.tsa.gov/travelers/airtrav...rial_1059.shtm it says
Travelers with Disabilities and Medical Conditions
Medications
Additonal items you may bring include:
Liquids including water, juice, or liquid nutrition or gels for passengers with a disability or medical condition;
Life-support and life-sustaining liquids

Has TSA declared Dehydration to be "Not A Medical Condition"?
Has TSA declared Water to be "Not A Life-Sustaining Liquid"?
Can TSA get the Surgeon General to put this New Think Not Overthink redefinition of life in a letter?

"It is unlikely that additional changes in the liquid, aerosol and gel policy will be made in the near future." Sigh.
