Ballanchine's Ballerina

I bought a big blue foam belt for my husband years ago when I was trying to get him to join me at the pool. Recently I came across it and strapped it on and swam my laps. That night my arms were aching. "That's from using the belt, its extra weight" my physics teacher husband told me. I was working my arms harder having to tug the belt which seemed weightless to me.

Yesterday I was swimming with the belt and I felt like I was being held up by a tall man's arm. I decided I finally was a tall long necked ballerina and George Ballanchine was dancing with me underwater.
