annie hall//forgot my mantra - me

Science question....

My nephew's having a Harry Potter party for his birthday next month and we were going to do a 'Divinination' class. We have goldfish bowls for the crystal balls and Sis had the idea of having colours in the glass so that it looks like there's a 'vision' coming through. Does anyone have any ideas of how that might be done? We tried adding food colouring to ice cubes and putting them in the bowls full of water to melt but it didn't really work because it just fills the bowl rather than having wisps.

Any suggestions?
