The Titanic Duck

I have been in Northern Ireland for the last couple of days on a visit (to HMP Magilligan). This meant staying overnight in the Stormont Hotel. This hotel is one of a chain where they leave you a bath duck - with their chain name - as a present (despite mostly only having showers in the rooms). This visit, they had changed the duck from a suited one to a "Captain of the Titanic" themed duck (because the city is the home of Titanic Belfast). Here is a picture of one. I brought my duck home and gave it to Bea.

Today I was telling my colleagues about it. One of them listened to the story and said: "I don't know how to put this delicately, but, does this duck... float?"
