This occurred while recreating [this post](https://www.reddit.com/r/chemistry/comments/1sdwxbi/ipa\_and\_di\_water\_mixing\_effect/) mixing IPA and water.

I noticed something a little strange. The IPA droplet specifically seemed to "attract" itself towards the existing water droplet. You could say this happened due to the angle at which I placed it, but it happened regardless of the dropper angle. In other tests I did the attraction got even more pronounced as the droplets got closer and a significant change it droplet shape occurred before they even merged.

Does anyone have any literature or explanations behind this? I'm guessing it has to do with vapor pressure and evaporation changing the behavior between the two surfaces.

I've wanted to do this for so long and I finally got it
