Mining Mercury
Mercury, the only metal that's liquid at room
temperature, is mostly mined from a mineral
called cinnabar. When the cinnabar is heated, the mercury turns to vapor.
Then it's condensed into a liquid and collected.

Hairy Ant Impostors
Velvet ants are colorful, hairy -- and not really
ants. They're wasps that live in the United States
and South America. Only the males have wings, but
the females have sharp stingers that cause super
painful welts.

She Invented a Language
At 12, Rachel Zimmerman invented the Blissymbol Printer
as a science fair project. Her software used a special
touchpad to turn a picture-based language called
Blissymbols into actual words -- allowing people with speech-

Frills and Thrills
When the frilled lizard of Australia feels threatened, it fans out a hood-like flap of skin on its neck, rears back, and hisses! If that doesn't work, it makes a mad dash for the trees --
which is where it lives most of its life.

Forest in the Clouds
A cloud forest is a rare type of rain forest on a
mountainside. Trees, ferns, and other plants draw
moisture from the clouds that wrap around the slope
-- thanks to a process called horizontal
precipitation. (Precipitation is another word for rain.)

Stinky Rocks
A sulfide mineral called arsenopyrite smells like
garlic if you crush or heat it. The sulfur in the rock
reacts with oxygen in the air, creating that familiar
powerful scent. Just don't try to cook with it!

Swimming Swamp Birds
The hoatzin is a primitive South American bird that
builds its nest over swamp waters. The young have claws on their wings and are great swimmers --
so if their nest is threatened, they just drop
into the water, swim to shore, and climb back
home!
