This week we have just one puzzle for you to ponder. It’s a very simple puzzle to state, but it leads to all sorts of debates and arguments. It is a good one to ask in the pub!

A person is sitting in a rowing boat that is floating in an artificial pool, and they are holding a brick. The person throws the brick out of the boat into the water, and it sinks to the bottom. Once the ripples have died away, has the water level risen, fallen or stayed the same?

As usual you can post the answers as a comment on this website, reply to the post on Facebook , or retweet or reply on Twitter @quizmastershop.

We’ll give the answer and explanation on Monday morning at 9.00 as usual.
