All this fuzzzz... freezing, okay. But nobody I know takes a freezer on a holiday... And forget the dangerous version of Cyanide; IF they catch you at the airport, you will need a damn good excuse not to land in jail.
So, use ethylacetate. But don't buy the expensive version, the lab-jars.
Just buy simple nailpolish-remover, containing ethylacetate (so NOT based on alcohol, the other version; read the contents carefully). This stuff is very cheap and without questions carried in your luggage (NOT handluggage though :o ).
