They were carefully packed with the lids on tight when you left, and now their contents are all over the inside of your suitcase. How come toiletries seem to spill so easily during travel? However, when you board a plane, the risk of spillage gets even worse. Air pressure changes in the cabin of an aircraft make gases expand, including the air inside a toiletry bottle.

When that air expands, it can rupture the container, creating the sticky explosions that frequent flyers are so familiar with. To keep the interior of your bag free of toiletry gunk, start with simple plastic wrap —yup, the exact kind of plastic wrap you have sitting in a drawer in your kitchen.

Unscrew the cap of the bottle, put a layer of plastic wrap over the top, then screw the cap back on to keep the plastic in place. This will help prevent the leaks that happen when lids get loose or start to come off.

When flying, you can reduce the risks posed by air expansion by removing air from inside your toiletry bottles prior to boarding.
