How do you type that sound for blowing air through pursed lips?

I was doing so well earlier this summer with keeping the blog up to date. But then my new camera broke and we took it back. They didn't have anymore of that same model, so we decided to wait to purchase a new one until after we did some more research. We are still waiting. So I am now attempting to do some research after which we will go buy a new camera - just in time for the holidays! Stay tuned.
