Oh sure - got it! An IV drip :)

Thanks for the hint

Kelly, sometimes it is really difficult to find a correct translation for things we normally don't use in everyday life. I looked up the word "Infusionsset" (I am not even sure whether this is the correct denomination in German) at dict.cc and got "infusion set" as the answer but when I googled for "infusion set" now, I did not get links to articles about exactly what I meant.
Probably, "IV line" would be the correct term.
It is a PVC tube, about 4 or 5 feet long, used for intravenous therapy. At the upper end, which, when used for its normal purpose, has to be connected to a bag or bottle with saline or other therapeutical fluids by a plastic needle, there is a drip chamber where you can estimate the flow rate. At the lower end, there is a connecting piece where the needle can be attached that has to be inserted into the patient's vein. In between both ends, there is a roller slide clamp for regulating the flow. I removed the plastic needle and opened the upper end so I could fill in some water. Perhaps I should glue a funnel to it in order to have bigger water reserves. Of course, there is no need to attach a needle to the lower end.
Now I hope it is understandable what I mean, whether the complicated medical denomination for this simple tube is correct or not ;-)

Thank you for your interest, Nico, Kelly, Traveller and Olaf.

Trav, I think you can do this too. This is one of the pics from my second try in water drop photography so you can see that I am still a beginner. Only a small part of the 250 pics were keepers.

There is nothing very special about the setup. I filled a glass bowl with water, put it into my kitchen sink on a purple cloth and placed a piece of yellow plastic material behind it.
The drops came from an infusion set which I bought for cheap money at the local pharmacy and which I had fixed to the cupboard with adhesive tape. The device allowed to vary the dropping speed and, as an advantage over an eye-dropper, my hands stayed free.
I used a tripod and focussed manually by means of a ruler which I temporarily laid on the bowl as the focussing target. DOF is always shallow at scales like this, so focussing is very critical.
The light came from an external flash. I think it would also be possible to use an internal flash but it is nice to experiment with different light directions. Setting the EX-580 to strobe mode also produced some interesting results.
It took me some practice to find the appropriate timing in order to catch each drop at the right moment. I got better results in single shot mode than shooting continuously. I admire people who are able to catch the moment when drops collide from opposite directions, forming beautiful shapes, but I am far from this skill.
