Why are liquids over 100ml not allowed on planes?

Liquids over 100ml are not allowed on planes due to security measures implemented by airports worldwide. The restriction was put in place after a failed terrorist plot in 2006, known as the “Liquid Bomb Plot.” This plot involved terrorists attempting to mix liquid explosive materials on board the aircraft to carry out a coordinated attack.

To prevent such incidents and enhance passenger safety, aviation authorities decided to limit the amount of liquids that passengers can bring on board. This limit is commonly referred to as the 100ml rule, and it applies to all types of liquids, gels, creams, and pastes. These substances must be placed in individual containers not exceeding 100ml and placed in a clear, resealable plastic bag before going through airport security checkpoints.

The reasoning behind this rule is to ensure that potential liquid explosives or dangerous substances cannot be brought on board aircraft. By restricting the volume of liquids, it becomes more difficult for terrorists to smuggle dangerous materials onto airplanes, reducing the risk of a catastrophic attack.
