Overview
- The traveller initially planned to test security with a two‑litre bottle but switched to a 125ml hairspray, which cleared the X‑ray without challenge.
- She recorded the attempt despite a posted no‑camera sign and described feeling nervous after noticing increased security.
- Heathrow’s published guidance still requires liquids in containers of 100ml or less in a single clear bag for most passengers.
- Viewers questioned how the item passed screening and noted that some Heathrow scanners do not require removing liquids from bags, though the 100ml limit applies.
- Coverage notes that several UK airports, and some specific routes such as from Birmingham and Edinburgh, permit larger quantities due to upgraded scanners.
