I love chocolate fountains - as long as they belong to someone else.
My sister has one and you should see the mess of her table and carpet after we have had a family "do". Mind you, that might be something to do with our family's table manners. lol.
Yummymum, if you type 'chocolate fountain' into the Answerbank search box, a list of threads about choc fountains will come up. If you're thinking about buying one, you might find some of the threads of interest.
(You may have already done that, and if so, disregard this post!)
