Oil for flow visualization

[MarioGameTV]

Hi Guys ,

I wonder if there is existing something like oil/color for watercooling with i will just add few drops to my mayhems pastel ice white so flow will be really nice visible but will not destroy nice ice white color

I'm sure i seen on youtube ages ago some dude with this but i cant find it now

Thanks for help
