Now that I&#8217;ve selected my nozzle (a 1\/4&#8243; coupler that joins the 1\/8&#8243; vinyl tubing in polycarbonate) it&#8217;s time to scale up to full six foot tubes.<\/p>\n<p>Although all of my calculations told me that everything <strong>should<\/strong> work with a six foot acrylic tube, you never really know if something is going to scale up correctly until you try it. For example, here is a list of possible problems with scaling up (ordered by probability):<\/p>\n<ul>\n<li>The air pumps, which are rated to a max pressure of 350mmHg (basically meaning they can just barely blow a bubble into a column of mercury 0.35 meters high, or deliver 6.7 psi), won&#8217;t actually achieve their rated pressure, and be unable to blow a bubble into a 6 foot high column of water (4.7 meters of water is equivalent to 350mmHg&#8230;but still&#8230;.)<\/li>\n<li>The bond holding the nozzle and bottom of the acrylic tube which worked fine for 1 foot of water would spectacularly fail when loaded with 6 times the pressure.<\/li>\n<li>The Acrylic column won&#8217;t be able to support the water pressure, and will burst. (Even 1\/8&#8243; acrylic is relatively strong, if brittle, so I wasn&#8217;t really worried about this one&#8230;)<\/li>\n<li>The cyclic pumping, combined with flashing RGB LED&#8217;s would interact in a heretofore unknown way to produce fusion, a la Chain Reaction (1996). <\/li>\n<\/ul>\n<p>Fortunately, everything worked just fine. What does an air bubble look like rising thorugh six feet of water? I&#8217;m glad you asked.
