The classic silver tree demonstration! Very simple to set up and perform, it's great to introduce kids to the world of chemistry.

The subtle things I mention in the video:
1) Tiny flecks of silver crystals falling off the copper wire.
2) The wavy mirage-like effect of mixing liquids, coming off the copper wire and copper goes into solution. I've noticed this in other videos before, but never for this experiment!
