Roll out a piece of gold colored fondant (tint with 10 drops of yellow to 1 drop of red) and cover the ball cake. It may bunch up a little at the bottom, that's OK because we're going to cover that up later. Now get out your alcohol again and some gold luster dust. Mix a tiny bit of alcohol with some luster dust and paint your Holy Hand Grenade a lovely shade of gold. You may have noticed that the Holy Hand Grenade looks a little lumpy, that's OK too, the original looked suspiciously like it was made from a coconut.
