Does it have to be water, Howard? I tried one with milk a few years ago, and would be interested in trying something with paint after watching this cool video. In it two guys pour paint on an old speaker and turn it up to full volume while recording in super slo mo.
Ogga, playing around with milk or paint could be mesy fun - rather you than me - although in fairness the theme is water drop and there are some entries already in. So I think we had better stick to water for this week. Of course you can colour it or thicken it I suppose, as long as it water to start with.
Sorry to hear about your ceiling Paul - make sure it doesn't collapse on top of you.
Just spent some time mucking about with water and sundry bits and bobs. Like Alan I don't have any retorts, and I can't find my microphone stands anywhere (how do they manage to hide?), so I used a step ladder with an old bit of wood on it to make a high up platform for an old 2 litre plastic bottle to be the header tank, got a piece of plastic tubing and fixed it to the head of an (unplugged) desk lamp placed about 40cm above a Pyrex™ bowl on a workmate in the garage. I didn't bother with a remote release, just squeezed the shutter gently. My main problem was focusing. I was using the macro lens, which I think was a mistake as it does not have sufficient depth of field to get the whole of a splash sharp.
I did try with on camera flash with the Lumix, but that was just too bright, and I didn't have time to muck about too much with that. I took some pictures of the setup, but then deleted them by accident. File recovery software can't find them, alas.
