We upgraded my wife's iPhone so I had an old iPhone 5 lying around. I thought -- hey! I can do something with that.
I used Dutchmogul's rubble to mix a box top and bottom that forms the magic pool.

Find a GIF online and play it using the iPhone's browser. Turn "screen lock" off so that the energy pool doesn't shut down in the middle of play.
Thank you to Delving Decor: Rocky Rubble (28mm/Heroic scale) by dutchmogul
I printed using 5 shells so the bottom would be strong.
