Ok a new type of quiz game. I'll explain the rules:
Each day until sunday I will post a question here.
The questions are to test your resourcefulness not your knowledge therefore using google, encyclopedias etc are allowed and encouraged.
in other words come by the answers by whatever means you can (except by asking me

)
Answer is to be Pm'ed to me. I will post the correct answer with the next question and we will have a little roll of honour at the end.
Best of luck.
First question a fairly easy one to get you going...
How many martian (the planet) days are in an earth year?
