Spectacular, fragile, magnificent, the cascade of golden bubbles is part of Champagne legend. The champagne fountain is not that hard to do. All it needs is for you to organise your coupes, (or flutes, or wine glasses) on a stable and flat base. 

The key is to place your first glasses in terms of the final desired shape: four for a square, three for a triangle, only one for a round pyramid – the other glasses are then placed in concentric circles around the first. At every level, place your glasses at alternate intervals. Once the construction is finished, pour the champagne from the top: when it flows, it fills the glasses, layer by layer. Cue applause!
