This video clip is in German, but I don’t bother to do it again in English because the content is clear. It is my hack for the modified set of bottles. As you have read, my bottles are closed with a cork (well, apparently), and therefore it is not possible to lift the stack and the tube in the traditional way (gripping inside the bottles from the top and lifting them).
I solved this with a bendable metal clip that is fastened to the innermost bottle on the inside, so it protrudes over the other bottles and the tube.
I think this is an excellent hack and makes the handling of the tube (and bottles) appear natural. Give it a try. Of course, some routines have to be adjusted (so Ken Brooke’s) to make this work, but it can be done.
