The ancient ancestors realized that building structures and machines to harness water to provide transport, power, drainage and irrigation was vital to the success of their civilizations.
This episode explores some of history's most ingenious, yet lesser-known engineering solutions.
In the last episode of the season we'll learn about sensory tricks - visually-evoked auditory response, retinal fatigue, Müller-Lyer illusion, Ames room and synesthesia.
In this episode we learn the diference between Iridescence, Chemiluminescence and Bioluminescence. We also learn about Gemstone Coloration and Mechanical Plant Defenses.
How are Rainbows formed? What does it mean to see a Mirage? And when we see a spinning dancer why one can either perceive as spinning clockwise or counter clockwise?
What is the Body Transfer Illusion or the Moon Illusion? We also explain how the Autokinetic Effect and the Stereoscopy work!
Terry and Larry go on a swashbuckling adventure when they test two scenes from the 1920's film, The Black Pirate starring Douglas Fairbanks, Senior. Terry will see if he can knock down a ships mast with a canon, and then test gravity as he slides down a sail with only a knife.

Each rocket that gets fired off has an impact on the atmosphere. Will Earth be able to survive hundreds, or even thousands, of fuel-burning rocket launches every year.
Once we've managed to get a handle on building structures to help us live on the harsh, dangerous surfaces of other celestial bodies -- why stop there?
Human needs have always created opportunities for human greed. And energy might be the most crucial need of all. Could we end up paying a subscription fee for sunlight?
Space is home to crucial resources, important discoveries, and big potential profit.
Stars are a bit like human beings. They can be warm or cold, they come in all kinds of shapes and sizes… and, let's face it, they can be dim or bright. Recent discoveries suggest the number of stars in our galaxy alone may exceed 200 billion.
For an instrument first developed as recently as the 17th century, the telescope has travelled a long way. The latest version of the once-humble telescope will be going a lot farther – carrying us ever closer to the first light.
