A cube made from drinking straws can confuse your brain.
Without depth perception, random lines can become a chair!
Learn how to fly with this neat mirror trick.
Find order in well-mixed chaos.
Make a home for a colorful community of microorganisms.
Suspend a ball in a stream of air.
Does it matter which end is up?

Suspend an object in the air by blowing down on it.
A bicycle wheel acts like a giant gyroscope.
Stare at one color—but see another.
