Here is the cake that I made for my daughter's glow in the dark party that was held at Glowgolf that was lite with black light. I was hoping that the MMF would "glow" but it didn't. You could see the decorations on the white but not really glowing. The vanilla frosting that I used to fill the layors did glow a light pink. I did make the jello that was recommended to me with the tonic water, it glowed blue, but did not photograph well. Unexpectedly the purple forks we brought glowed almost white.
