Stan Kann used to talk about a lady who kept insisting she had seen in a magazine a vacuum cleaner attachment used to lift refrigerators! Of course he thought she was kookoo until she brought him the article! He showed it to me once. It was a bad photocopy so it was hard to make out how the apparatus worked, but it appeared to have two long flat "fingers" that slid underneath the refrigerator. Then when you turned the vacuum cleaner on with the hose in the blower end, a turbo-powered fan would purportedly exert enough air-lift under the refrigerator to make it move like a hovercraft. Anyone ever seen or heard of this device?
