"Spark Trees" are a fun and interesting
product of particle accelerators. They are created at the
Idaho Accelerator Center using a high energy electron beam
from a linear accelerator. The electrons penetrate the pastic,
causing a very large electric charge to build up. This electric
charge is released by striking the plastic with a sharp object.
The regions where the electrons move escaping the plastic
creates the "branches" and "trunk" of
the spark tree. Like snowflakes, no two are exactly alike.
These spark trees are attractive, producing a brilliant display
when light is shone through them. Place a spark tree on a
multicolored light base for fascinating shades, gracing a
desk or bookshelf with an intelligent and colorful display.
