This Christmas I just brought some from NY JFK to Phoenix, I put it in a ziplock, then I put that baggie in a bag with pepper( I saw it in cool hand luke, when the dogs were chasing him he sprinled pepper on the ground so they couldn't follow his scent)I put in my uderwear ubtil we were in the sky and then I went to the bathroom and put in my pocketbook, it was so much easier than I though
