Wedding cake cutting/fountain question...? - cake fountain

What sources do you think of the wedding cake? And if they are made of plastic, you can always look good? How much water would need a rule? In addition, if the bride and groom cut the cake, you cut through all the layers with a knife and they even cut a piece of cake just the base coat? Let me know please, thank you!
