Liquids provide a visually appealing way of moving the glowsticks in mid-air.

Liquids in the non-glowstick, dancing form means giving the illusion that two hands are following a path that looks very watery. The figure 8 is simply a liquid that follows a path. The inverted-figure 8 is in my opinion, a liquid version of the figure 8 that looks pleasing to the eye.

In terms of glowsticking, liquids are accomplished usually by having two glowsticks follow each other. This can be done in a multitude of different ways.

Traditional Method involved the most common way of holding the glowstick-- the eagle claw method. You tuck them in between your fingers on each hand and you horizontally make them follow each other in a wavy motion.

Horizontal Method (to my knowledge, iloveraving.com glowstickers were the first to do this). In this method, the glowstick is held at the tips, and they follow each other much like a train with multiple cars would.

The Rubber Pencil Method (to my knowledge, iloveraving.com glowstickers were the first to do this) -- takes advantage of the rubber pencil affect that is commonly done when you were a kid. You can make liquid type effects using just one glowstick.
