Fulgurites

Saw the coolest thing I've seen in a long time in a book yesterday.

It was called a "Fulgurite" and is caused when lightning hits sandy ground, fusing the sand into a lightning shaped hunk of rock. Very cool!

Got my second fish tank filled tonight and the heater and pump/filter are working. All I need now is a lid.

Just watching survivor at the moment, it's getting really interesting now. Only six to go with people with all sorts of twists and people changing their minds.
