I like how the bubbles float up much slower and are more defined. Also, because the Glycerin has a lot of &#8220;micro-bubbles&#8221; in it, the light from the RGB LED&#8217;s in the bottom of the tube diffuses out of the mixture much more, and gives the whole tube a colored glow effect.<\/p>\n<p>One problem is that if I want to make larger bubbles (than in the video above) I need to increase the size of my nozzle.
