Even easier than that (from a previous thread). Get a dental vibrator from ebay (new w/shipping approx $55). Go to Lowes & get a pvc toilet adaptor with `4.5 inch inner diameter & glue it to bottom of a small lunch tray. It is removable for cleaning and variable speed. Total cost is about $60. Will look like one on ebay being sold for $170. Candy mold shaker Mark
