Rule basis: Treated as a gel at airport security. Based on general aviation security guidance — rules can vary between airports.
What to do: Default to 100ml per container in a single 1-litre clear bag. Anything larger goes in checked luggage.

Three separate rule systems · Any one can stop your item
In cabin baggage
Most airports treat this as a liquid. The standard rule is containers up to 100ml, all fitting inside a single 1-litre clear plastic bag, with one bag per passenger. A few airports with new CT scanners (e.g. London Gatwick, Edinburgh, Bristol) allow containers up to 2 litres — but you cannot count on it both ways.
In checked luggage
Fine. Keep cool — heat changes texture.
TSA has confiscated more slime than you'd think. Bring a small pot or buy at destination.
Examples
- •50g pot: cabin OK
- •500g tub: hold luggage
