I was thinking today and wondering about just hiding it in ur sock, I mean you would want to heat it up beforehand n all, but I would think that would be a pretty safe place to store. I mean it's not like they search you, the most they do is have me empty my pockets, so I was thinking just putting it in your sock would be a safe place cause the bottle is small and it wouldn't fall out as easily as if it was hidden somewhere else. But I haven't tested this so I don't know if the temp would drop too much, but I know when I go to take the test the time from between when I go from the car in the parking lot to the bathroom usually isn't more than 20 or 30 minutes. Would the temp be able to drop much in that time?

I might have to test this out...
