Cracked.com wrote a very informative article about performing tricks that appear incredibly dangerous.
As you will see if you click on the link above, there are various
death-defying stunts that are secretly easy to do.

As it turns out, the only trick to deep-throating a sword is overcoming your gag reflex. When something enters our esophageus, it contracts to push it down toward the stomach. This reaction occurs automatically, whether we are downing a burger and fries or 22 inches of forged steel.
The picture up there tells the story. Heat rises and fire goes up -- that's why you can hold your fingers on either side of a candle but put a finger right over the flame and you'll be in tears. Likewise, the flame coming off the end of the torch wants nothing more than to burn your face into Eric Stoltz from Mask, but you can safely get it into your mouth if you give the heat a perfect, vertical, invisible chimney to rise up out of.
The karate chop is one of the most efficient movements the human body can do, exerting thousands of newtons of force. If you hit the blocks in the exact middle and -- this part is important -- then follow through with a pushing motion to complete the chop, it prevents the blocks from rebounding from that bend. So the break hinges on this critical follow-through.
Because you're distributing your weight over hundreds of nails, you're not putting much weight on any one point. Certainly not enough to let the nail punch through your skin. As long as you spread out the weight, you can lie there for hours without getting a scratch. It's not even all that uncomfortable.
If your feet are moist, you have the Leidenfrost effect protecting you, which occurs when you have a layer of liquid between an object and a major heat source. The water creates an insulating vapour to greatly reduce heat transference, essentially encasing your feet in a fireproof mist.
Water has a very high heat capacity, while the coals have a very low heat capacity. Therefore, the temperature of your feet will change less than that of the coals as you walk across them. And because of water's high thermal conductivity, rich blood flow in the foot can carry the heat away, diffusing it upward.
