Well, here we go.
Over the next 24 hrs, the UK will decide whether it wants to stay in or leave from the EU.
There has been a lot of nasty campaigning from both sides, not much in the way of facts and figures just lots of rhetoric and ill-feeling from both sides.
I'm guessing most of the planet is curious to see which way this one is going to go and to be honest, no-one has any idea which way it is going to go. The polls have swung one way, then another and it's likely to be down to who can get their vote out.
And now we just have to wait until Friday morning to see what the result is.
