A few days ago I watched 'Paint Splash Ep 111: Take & Make Great Photography with Gavin Hoey: Adorama Photography TV'. I've got some left over tiles from our house from the bathrooms I think and setup the below shot using the sun as my light source.
I used one of with soy sauce as my dripper, hand held. Of around 50 shots the one below is the best, will have to try this again.
Since I was already setup I wanted to get some shots of water splashes. I've added a few of the better ones below.
