Now that is exactly what I was looking for. Thanks Sherpadog. I will be conducting some tests as well. I will be out of the country for about a month, but when I return I should have some time. The cotton balls with PJ and then dunked was good info. And no, Scafool, I am not looking for what a terrorist can carry on a plane, not that some PJ and cotton would do much to an aircraft except [censored] people off.. I am looking for what is commonly carried anyway and how it can be used. I travel very frequently, and having candles in my pocket with a PSK makes airport security nervous. A small tube of PJ or chapstick is no issue for anyone.
