Geobacter like a bit
of current for their tea.
These microbes stay alive by
eating ELECTRICITY.
Connected by their hair-like strands
these wired-up microbes grow
and form a film of circuit-slime
that makes a current flow.
Feeding on electrons
can you guess what they excrete?
Electrons in – electrons out.
It’s weird. But rather neat!
