Just tried out water droplet photography today after obtaining some tips from youtube. Here is the result.
The blueish look is obtained by changing the white balance to tungsten mode. My light source come from two table lamps behind a white sheet. 
The vacuum cleaner tube is to hang a punctured plastic bag filled with water. The water droplets from the plastic bag fall into the black bucket below, which is filled to the brim with water. 
I used canon 5D markII with a 100mm macro lens. Because the light source isn't that strong, I need to push the ISO up to 5000, so that I can shoot at 1/1000 s and F8.0.

It seems that I should have used an even faster shutter speed because the falling droplet still have some motion blur at 1/1000 s!
