When I saw @allisonrap's picture "Oops!"(http://365project.org/allisonrap/365/2012-05-07) a couple of days ago, it set me thinking about my nemesis, the water collision shot. It suddenly occurred to me that maybe I didn't need the drop to hit another drop to get the shot I wanted, just something a similar size.
This is a combination of milk, water, glycerine and white poster paint - combined in a totally random recipe - and dropped from a pipette onto a drawing pin head. The flash was triggered by a rather thrown-together laser trigger built by my OH (yes, he's awesome) from a laser pen & bits of the sound trigger.
I'm really quite chuffed with the result. :)
