Interesting tidbit re: the density of marzipan mimicking that of explosives!
>>>Another reason many people have their bags pulled is because they have marzipan, also known as almond candy dough, packed inside their suitcases.
“Don’t ever pack marzipan in your luggage. It has the same density as some explosives, so your bag will be removed and you’ll be called from the plane for a bag search,” the Dublin baggage expert said.<<<
It's like Aaron's rod that budded!
Peanut butter too. I had a brand new, unopened jar confiscated. They said it shows up as explosives in the scan.
So does Kaopectate.
