Ja, pga att den går som vätska måste den ligga i plastpåsen.
Skuggan, då har hon kanske läkarutlåtande med sig? Sprutor är såklart högt på terrorlistan, ännu värre än saxar, pincetter osv pga att de även kan ha dödligt innehåll. Såhär skriver BA och det är samma regler hos de flesta flygsällskap:
None of the following are allowed in British Airways aircraft cabins (similar regulations are likely to be introduced by other airlines):
Toy or replica guns (plastic or metal).
Household cutlery.
Knives with blades of any length (including steel nail files).
Paper knives.
Razor blades.
Tradesmen's tools.
Darts.
Scissors of any size.
Hypodermic syringes.*
Knitting needles.
Sporting bats (including rackets, cricket bats and golf clubs).
Billiard, snooker, or pool cues.
Catapults.
Corkscrews with blades attached.
*Customers who require the use of hypodermic needles for medical reasons (for example, diabetics and customers with allergies), will be asked for proof of medical need. Please be advised that customers carrying any of the above items (with the exception of hypodermic needles) will be asked to place it in their hold baggage. Customers carrying hand baggage only will be asked to surrender the item for disposal by British Airways.
