Thanks for the comments. The blurriness is not a lack of focus, it's motion blur. I took this around 10pm at night in my kitchen, and there just wasn't enough ambient light to get fast enough shutter speeds to freeze the action. I plan on re-taking this shot in natural light to try and improve upon it.
I couldn't see what this was at 1st. I tried turning it upside down and everything. I see it now. It's a drop of something hitting the surface of something. It's a splash! Really cool.
