A chocolate fountain is a device for serving chocolate fondue. Typical examples resemble a stepped cone, standing 2–4 feet tall with a crown at the top and stacked tiers over a basin at the bottom. The basin is heated to keep the chocolate in a liquid state so it can be pulled into a center cylinder then vertically transported to the top of the fountain by an Archimedes screw. From there it flows over the tiers creating a chocolate "waterfall" in which food items like strawberries or marshmallows can be dipped.
The Jean-Philippe Patisserie at the Bellagio Casino in Paradise, Nevada is home to the world's tallest chocolate fountain.[1]
