Splat Glow In The Dark Temporary hair dye?

Okay before i buy it i want to know, how long it will usually last? If it fades will it look really bad? Um i have plain semi light brown and dark so medium brown hair so will it put on okay? and how much are in the bottle because i have medium thick hair and i want to put in streaks and my side bangs? Does it really work? And does it look okay and cool when not glowing in the dark? Lastly, how much dye do i have to put it in? How long do i wait? Please respond with experience. And honestly, i really need to know. Also does the blue or pink look better? Remember!! GLOW IN THE DARK... not the plain ones..
