Ok so a good friends 30th birthday is coming up and my friends and I are throwing her a disco themed surprise party. She knows a party is happening and dropped a hint about wanting a disco party so we decided to roll with it. The party is a week before her actual birthday. So I'm a Novice cake decorater. I've done it professionally but the place I worked at was very particular in the cakes it made so didn't get to be super creative. But I enjoyed it for awhile. It is now more of a hobby for me. Anyway I was thinking of attempting (I plan to practice) to make a disco ball cake. I think it would be cool and fun. I think to make the shape I'm going to make 2 cakes in my batter bowl and put them to together to make the ball shape. I'm pretty confident that I can just frost the cake with a silvery colored frosting and use toothpicks or something of the like to make the indentations of the ball itself. I looked at Michael's today and found some silver sparkles that I think I may use as well. But I want to mostly use them just for the glittery effect. My questions are basically this: Do you think this will work? What color food coloring will make a silver? I was thinking of just using a little black but that's going to be more grey. So does anyone know of somewhere that sells silver food coloring? I'm open to any and all suggestions. I'm not interested in fondant. I've never used it and I don't like the way it tastes. I prefer to use buttercream, however the birthday girls wants whipped cream! I'm going to make it work one way or another but could use some suggestions and words of encouragement. Thanks.
