I'm checking my bag tomorrow (I know, I know, ha), and I'll be bringing some shaving gel along (Gilette Fuzion, for those interested). I have always brought my electric razor before. I'm no science whiz, but I'm a tad worried about the heat and air pressure doing some numbers on my compressed shaving gel can. I have visions of blue shaving gel blasted all over the inside of my bag. Should it be ok in a separate plastic bag, or am I getting worried about nothing? Thanks!
