Chocolate Fountains

Why does the falling curtain of chocolate on a chocolate fountain pull inwards rather than straight downwards?

One mathematics student figured out that chocolate fountains follow the same pattern as ‘water bells, ‘ which fall inwards because of surface tension. You can make your own water bell at home by  putting a pen vertically under a tap with a coin flat on top, and you’ll see a bell-shaped fountain of water.
