Whirling Dervishes

I walked into the living room today and was treated to a show.  My two daughters were giving us a Whirling Dervish show.  Both were spinning standing in place.  I don't know what it is with children with seeing disabilities, but they like to spin.  They don't get sick.  I'd get sick doing what they do.  I think we should get them the hats and skirts that Turkish Whirling Dervishes wear.  We could bring them out and public and seek tips for their show.
