why does liquid foundation explode in airplanes?
I have always wondered why so. I have always heard of that happening to people a lot and i never understand why. it has never happened to me and i have traveled with liquid foundations in squeeze tubes before. just for protection, how can i prevent this? of course i can put the tube in a ziploc so it won't get all over but can i do something so that the foundaton won't explode at all? thanks
