On the tenth day of Geekmas, you can win… a vintage authentic Hollywood souvenir stubby holder as seen in the movie ‘The Dish’! Keep your drinks cool with space age technology! We have 10 to give away.

To win, solve this riddle in our Facebook competitions app:

 

What am I? I have appeared on an Australian banknote. I am not small: I am bigger than the moon! I contain some water, but there is no chance of rain. I am named after a Portuguese explorer, but am invisible to those in his homeland.

 

Today’s prizes are courtesy of our online Parkes Dish Shop, who have an awesome range of  geeky gifts, souvenirs and clothes.
