Body: <p>I'm planning on doing a replica of the Belaggio fountains. I can't find it now, but I remember somewhere I saw someone do a build where they threaded a transparent tube through some 1 x 1 round bricks to make a &quot;bendy&quot; transparent column. I'd like to use this technique to make some moving fountain sprays.  Does anyone know anything about such a technique, and what parts I need?</p>

  I'm planning on doing a replica of the Belaggio fountains. I can't find it now, but I remember somewhere I saw someone do a build where they threaded a transparent tube through some 1 x 1 round bricks to make a "bendy" transparent column. I'd like to use this technique to make some moving fountain sprays. Does anyone know anything about such a technique, and what parts I need?

  If I'm understanding you correctly, you'll need 1x1 round bricks and something bar-sized and flexible to hold them together.
  
  Alex pointed out that the hoses typically used for this sort of thing aren't available in trans-clear. Pneumatic tubing has been produced in trans-clear, so it could be an option, but you'd need a different design, as pneumatic tubing will not fit through an open stud.
  
  You could use [fiber optic cable](https://www.bricklink.com/v2/catalog/catalogitem.page?P=x400c25&idColor=12#T=S&C=12&O=%7B%22color%22:12,%22iconly%22:0%7D):
