        I'm surprised no one has mentioned the easiest method of getting the empty spinner out of the upper barrel: simply crank the VT air up to 30 or 40 and the spinner floats up just fine without any of the complicated methods suggested earlier.

        We have enough undergraduate researchers and undergraduate labs using our 300 MHz Inova that I end up doing this once or twice a month. I've had to do this at least once or twice on our 500 MHz Inova as well. This should not be a complicated or time consuming endeavor; just use the VT air and your back in business in less than 30 seconds.
