Guinea Pig

The aftermath of an avalanche is a chilling reminder of the risks we take when venturing into freezing environments. Taking on the cold, Ryan is plunged into ice water, belted into a sinking car and buried alive in the snow to see how his body responds.

Going for depth in a dive chamber on land then trying out the real deal in the Atlantic Ocean, Ryan takes on one of the world's most dangerous sports - free-diving - to prove that the Guinea Pig isn't just tough... he's deep.

Hollywood has brought Kung Fu and Karate to mainstream North America but left the history, traditions and philosophy of these martial arts behind. Ryan explores those forgotten traditions and skills -- testing pressure points and getting battered with old-school weapons -- and discovers just how tough the original tough guys had to be.

A polyurethane suit and an afternoon of training is all that is between Ryan and a wall of fire as our Guinea Pig takes on the heat, but a twist of events sharply changes the outcome of his first experiment. Later, enclosed in a flashover chamber and engulfed in flames, Ryan has to rely on the firefighter's protective gear to keep his cool and hope the blaze is not too hot to handle.

Technology and cops go hand in hand - and not just in the movies. Using cutting edge less lethal technology to replace deadly force, today's weapons let police forces do their job and save lives. Ryan gets zapped, gassed, blasted and bombed in order to find how effective these futuristic weapons actually are.

Reaching new heights, the Guinea Pig heads up to see what it's like to step out of an airplane - at 30,000 feet! After intensive military flight training, Ryan experiences debilitating oxygen deprivation during the highest skydive a civilian can attempt!
