The Izzies' Fireworks are Surfing Electrons!
I just found the article below online. (I think surfing electrons might be just as magical as elfen fireworks!) "A group of physicists from Iowa State University have finally proven that the “most brilliant auroras are produced by powerful electromagnetic waves during geomagnetic storms,” according to a newly released study. The study shows that these phenomena, also known as Alfven waves, accelerate electrons toward Earth, causing the particles to produce the light show we know as the northern lights. “Measurements revealed this small population of electrons undergoes ‘resonant acceleration’ by the Alfven wave’s electric field, similar to a surfer catching a wave and being continually accelerated as the surfer moves along with the wave,” said Greg Howes, associate professor in the Department of Physics and Astronomy at the University of Iowa and co-author of the study.. . .proving that electrons surfing on Alfven waves can accelerate the electrons (up to speeds of 45 million mph) that cause the aurora,” said Howes.

Book Excerpt
Tizzy, the Christmas Shelf Elf
We feast and we frolic. (It’s kind of a perk
To celebrate ending our annual work.)
For after each elf belly finally is full,
We pull on our parkas and mittens of wool
Then, joining our hands in an elfentine ring
Which circles the Arctic, we dance and we sing.
Our finale is fireworks which fill the night sky
With curtains of color that shimmer so high!
