Minimal Summer Drink in SVG

I tasked myself to create an animation that reduced everything down to its most basic representation.

I went through several iterations of this, each time I removed something until all that was left were the basic elements required to represent pouring a summer drink (apart from the fizz - I couldn't help myself!).

You can see the original animation on CodePen here:
