Packing Liquids in your suitcase

So this pin  has the potential to be amazing.  According to this girl if you place a piece of plastic wrap under the lid of your shampoo, sunscreen, and so forth it will not explode all over due to pressure change.

Well... I did this, but failed to screw the lid of my conditioner on straight.... dun dun dun :(  Lets just say there were tears (also I had an unopened container of baby formula explode in the other suitcase... not sure which made me more angry.)  However none of the liquids that I got the lid on right did no leak.  I will have to try this again next time but for now I give it a hesitant thumbs up!
