Now, this is... WOW! I mean, just... WOW!!! I've read the whole 14 pages without pause (never done something like that before) and I'm really impressed. I don't even know where to start giving personal WOWs and THAT'S GREATs, so I'll sum it up for all the above posts:
AWESOME!!!
I even got the courage to share some of my creations. The combination between watching a purification column dropping 10 drops per minute and having a sheet of aluminium in reach results to the attached images.

Strange as it may sound, I think I like the Curious Goose the most. Especially since she flew away (I left her near an open window and the next morning she was gone

).
Funny story: The Goose also has another name. When I showed the picture to my girlfriend, her first reaction was:
Curious Goose? I would have called it "A lonely tree with two branches."
I had to admit, she really had a point there, so now the Goose (or the Tree) has two names.
