Lit bubble columns/bubble wall
I've been looking at these awesome bubble columns
that are so wretchedly expensive and dying to get one for my office. Note, I am sure they are worth every penny, but I have few pennies. For the link-phobic, a bubble column is a clear tube several feet tall with an aerator making bubbles and multi-coloured lights from beneath the column. Some columns are interactive and others have plastic fishies or balls that sail around inside. There is also a space-saving "bubble wall" that only runs 1L of water.
Anyone even have a clue as to where to start?
No pics, sorry, I didn't want to pull them off the website.
