How do make chocolate glow in the dark?  I have a cake order and they want chocolate drips down the side of a fondant iced cake to glow in the dark.  There are 5 different colors of drips and they want them to all glow in the dark.  They have access to a black light.  I can make the colored chocolate drips but is there glow food colors that I can paint over the drips?  Please help!  I have the cake order going out on November 22, 2019
