A blind person can drive a car safely by following instructions given by a passenger.


Adam and Jamie first tried driving while blindfolded but failed miserably. When a truly blind person was behind the wheel, he could drive fairly well. Adam and Jamie also tested the circumstance of the passenger (instructor) being intoxicated. This caused communication to break down and resulted in erratic, dangerous driving, much like the driver himself was drunk. Finally, the MythBusters speculated that a person rendered blind before they could get a driver’s license would lack preconceptions about driving, making following instructions less difficult than if they had previous driving experience.

It is better to hit a golf ball straight through a tree than around it because it is 90% air anyway.


Tory, having played golf since high school, hit 10 golf balls at a tree (the upper, foliaged portion), resulting in 6 going through, 2 bad shots, and 2 ricocheting off the trunk; Grant and Kari proved inept at driving. Grant then built a robot which only got 24 out of 100 golf balls through the tree. Tory also competed against the robot, getting 27 of 100 hits through the tree.

Metal cleated shoes attract lightning.


Two identical ballistics gel dummies were constructed. One wore metal cleated shoes, and the other wore plastic cleated ones. Both were exposed to simulated lightning, and lightning actually struck the dummy with plastic cleats in 6 out of 10 trials.

The shock wave from a C4 explosion can knock a golf ball into the hole.


This myth is based on the final scene of the 1980 film Caddysack. After recreating the circumstances in the movie, the C4 explosion failed to result in the huge fireball seen in the film, and the golf ball did not move as a result of the shock wave. For effect, Tory, Grant, and Kari later used gasoline to duplicate the fireball seen in the movie.

    I was just wondering if the Caddyshack experiment was done with the explosives underground, In the movie the C4 was in the gopher holes. I missed this episode but wish I hadn’t, it would have been interesting to see.

    where was the blind driving filmed? I missed that part of the show… where would an abandoned neighborhood hide in the bay area?

  3. robert carlson:

    The defect in the golf ball through the tree test is that they were missing the key figure of the density of the tree per cubic foot, giving a probability of a ball going through a single cubic foot.

    Only knowing that density figure can you correctly predict the chances of hitting your ball through the tree.

    Say for one cubic foot the density or probability of passing through is is 90 percent or .9. Then the correct way to to get the chances of a ball going through x consecutive cubic feet of tree is to multiply .9 to the x power. IF the path x is 10 feet then .9 to the ten is about .32 meaning only 32 percent of the balls will pass freely through the tree even though the density is 90 percent air.
    If the path was 11 feet the chances are .27 which is the success rate achieved in the golf espisode.

    They say that when u hit a golf ball with a driver that its not about how hard you hit the ball. They say that just take a smooth swing. I would like to know if it goes father with a smooth swing or the harder you hit the ball the farther it goes

    Re jordan:
    Here’s the entrance that Adam unchains part-way through the episode:

    (I was determined to find it after they had been to this place twice and mentioned that it was called Cypress Hills near Marina).
