Temporary ball bearings

I was thinking about the problem of moving a large cumbersome thing into place, a discussed in the "Liftease Panel Waltzer" idea. Moving with a machine is difficult because the machine must fit in and out of the place. Just sliding along the ground is hard because many things aren't intrinsically slideable - plus you might damage or scratch a nice floor (as I have done moving furniture). Ladling grease onto the surface is less than ideal because you are left with a huge mess.

A bag of small ball bearings, scattered about the floor and under the object, would allow large objects to be rolled across the ball bearings. New ball bearings would have to be strewn in the path, like rose petals. One could clean them up with a vacuum/magnet attachment. This would be OK, but who wants to clean anything up? Also, once you have the item in place, a bunch of ball bearings are wedged underneath and you have to get them out.

Solution: ice ball bearings. They have the rolling qualities of ball bearings - but if they get a little crushed or warm they then have the slippery quality of ice. Libreally sprinkle them under the item and in its path. Best of all - when you get your item in place, just take a coffee break. When you return the ball bearings will have melted and your item will have settled down into its place. These would be sold at hardware stores and places like U-Haul and Ryder for use by do-it-yourself movers. They would come in large returnable thermos bottles, charged with liquid nitrogen for maximum coldth.
