What in the eff?
My parents called from Paris and told me to bring a Tide pen with me when I met them, and I stuck it in my baggie. It made it through BOS, DUB and CDG. I also brought it to Barcelona, so it was fine in JFK and BCN as well. It's freaking laundry detergent. It's indeed a liquid, but what in the eff? I guess it's just one of those TSA things.
