Les battles extreme wind.

Les faces a fire ant infestation.

Les creates a shelter from the rain.

Les has a close call on horseback.

Les makes his own fishing gear. Will he catch dinner?

Les uses a found lighter, wood and a rubber shoe to build a fire.

Les journeys to a remote community in British Columbia where sightings of the Bukwas, or Sasquatch, are common and belief in the creature is a given not a myth.

As Les prepares to venture up a trail that has had reported sightings of the Bukwas, he finds an interesting and inexplicable display of bones and flattened grass.

Les uses his tracking skills and keen observation of the big picture to explain what caused some strange signs in the woods that some might consider “mysterious.”

Les looks over a vast forrest noting there is certainly room for an intelligent creature to go undetected, but proving whether it exists or not belongs in the hands of scientists performing observation based science.

No matter what he’s looking for, Les’ first objective is to survive in the bush. He talks about how he will ration his supplies for his night on the mountain, and reflects on what he’s seen so far.

Les knows that sometimes evidence can be misleading. By casting bear tracks he demonstrates how the bear’s steps can often be mistaken for a Bigfoot footprint.

Les believes the only way to prove Bigfoot’s existence is with scientific evidence, not anecdotes. He hides a battery of high tech, infrared, motion cameras to potentially catch something on film, covering his tracks along the way.

Science dictates the need for statistics about the mystery of Bigfoot for Les, so he uses his survival skills to hike deep into the mountain and search for caves or other shelters that could hold clues to its existence.

Les reviews a Bigfoot tracker’s evidence caught on film, and explains how "pareidolia" - the psychological phenomena of seeing human faces in objects might be responsible.

Les visits a Bigfoot hotspot in East Texas, and lays out a battery of high tech equipment in a controlled environment to gather something definitive during his stay.

Les’ guides Randy and Sonja believe the way to contact with Bigfoot is a softer, more spiritual approach. Les is game to try it.

After honing his skils and with the help of Hollywood experts, Les creates several casts to put before eminent Bigfoot researchers.

What would cause three men to cough up money to sit in the “VIP” section of the bus stop? It seems we all have an innate need for self esteem and status – even in questionable circumstances.

Our brains are trained to expect patterns. Watching someone go in a door you expect to see them on the other side. When they don’t appear, observers are baffled, but to those in the know it’s a slight-of-hand magic trick; a misdirection made possible by o

Subjects are given the same wine, but served with two different labels. They are convinced the wine with the sophisticated label is much better.

A person’s primal fear of what we think can hurts us... like spiders, can override anything. This is magnified if our human nature to help someone makes us more vulnerable.

When it comes to reactions, sometimes it’s our instincts that take over. When a stranger suddenly starts to fall in front of you, most will react without thinking to catch him.

We aren’t born with conditioning; it’s a learned response. For most of us these days one of the strongest conditioned acts is checking our phones. You hear the tone, you check.

Watch a man drag hapless strangers into lying for him in front of his wife. They become faux co-workers. Is it tribal mentality to protect him, conflict avoidance, or just kind of fun?

We take another look at how mobile phones have changed us. People are so actively focused on them while walking they miss a man hanging $20 in front of them.

What happens when people walking down the street get stalked by a toy lawnmower? Are we terrorized or totally cool with that?

Our fear of things like snakes, is deep and instinctual to protect ourselves from harm. But, it can go too far sometimes causing us to react before checking if the harm is real.

Mars is about half the size of Earth, yet has volcanoes that are much larger than the ruptures on our planet. In this web exclusive, explore off-world volcanoes.

Professor Showman and Dr. Thaller compare Earth dust storms to Mars dust storms.

Venus traps heat from the sun. Space probes discover volcanoes on this extremely hot planet.
