I think the plants I've seen categorized as wandering jew do not tend to just drip down in the way that I imagine you are wanting. The ones I have stick up in the air, even if they don't have anything to stick roots into. I only have two or three plants that I've heard in any context called "wandering jew," so I'd maybe wait for somebody else to corroborate or correct my thoughts on these plants.
NEHERP has a section on trailing plants that are inexpensive. I have only ever bought one of them; I can't remember its name, but it is very hardy and it just sort of trails down the sides of my viv. I replanted it in a new viv in this photo, although it hasn't had time to grow much:
^It's the green, tear-shaped-leaf plant descending from the driftwood like locks of hair.
