Macbook Pro Rainbow Screen?

[Ryan]

I was in my kitchen with my macbook next to me and I was filling up a cup with water, dropped the cup, water splashed onto the Macbook pro's backside. I was fearing it went into the fan, so I just wiped off the water and left it. I was watching a youtube video when the whole screen flickered rainbow and stayed there before turning off.

I plugged it in and turned it on and it was just a ranbow flickering. I did the Control Command R and P buttons to restart it and it came up fine but Im worried. What does it mean for the logic board if anything?
