You know the rule: no liquids over 3.4 ounces (100ml) in your carry-on. But why that specific number? It’s not random.

Authorities tested explosives. They found that any container smaller than 3.4 ounces couldn’t hold enough liquid to blow up a plane. So, unless you’re planning a very tiny apocalypse, your lip gloss is safe.

Bonus fun fact: That 3.4 ounces is exactly the size of a standard baby bottle or a mini wine bottle. Choose your poison wisely.
