While these Busters have examined all sorts of scientific phenomena, internet rumors, and other assorted "myths" -- some of which we still can't believe are true -- some of their subjects are nerdier than others. Here are our picks for the 10 nerdiest myths MythBusters has taken on so far.
10) Archimedes' Death Ray
This historical myth was so controversial the first time the MythBusters crew attempted it, it attracted the interest of America's "Nerd-in-Chief" himself, President Barack Obama. The story goes that ancient Greek inventor Archimedes invented a death ray by focusing reflected sunlight from polished bronze shields into an intense beam so intense that he used it to set fire to attacking Roman vessels. The first time the show tried it, the experiment failed, but Obama reasoned it could work if more shields were used. So, operating under "Executive Mandate," Jamie and Adam enlisted the services of an entire high school science class to redo the experiment. The beam proved hotter and more intense than their first attempt (which used only eight or so "soldiers"), but it still failed to set anything aflame. In the end, it was posited that the technique may have been used to blind Roman sailors, thus making their assault more difficult, but as a means of turning attacking ships into smoldering cinders, no way.
9) Duct Tape Survival
What exactly is nerdy about duct tape? Well, it's tough to put it in words, but there's something inexplicable about this miraculous substance's appeal to our kind of folk. I believe it takes the fevered mind of a certified nerd to look at a simple roll of grey tape, and wonder if one could make working black powder cannon, or a sailboat, or lift a car, or build a bridge... or even make a honest-to-God airplane (all these things have been achieved, by the way). A new duct tape specific episode is made whenever the MythBusters think of more new and wonderful possible uses. This recent season kicked things up a notch by stranding Jamie and Adam on a "desert island" with nothing but a pallet of the magic tape for survival (building shelter, finding food and water, signaling for help, maintaining mental focus, etc). They survived, obviously. Duct Tape is just that powerful.
8) Tesla's Earthquake Machine
Nicola Tesla has been a certified nerd icon for generations: Beyond the brilliance of his theories and inventions, his well-publicized feud with Edison branded him as the brainy outsider who fought against the dominance of a flashy competitor. He's like the smart kid whose science project was too complicated for the judges to understand, and thus lost out to the popular kid who built the biggest baking soda and vinegar volcano. Unfortunately, Tesla's brilliance began to fade into madness in his later years, and though some of his proposed inventions would later provide great material for science fiction, few of them were ever tested empirically. Enter... the Earthquake Machine. Using the principle of resonant frequencies, Tesla believed this device could destroy any solid object, and possibly even the Earth itself. It took hours of thankless work for Adam and Jamie to properly replicate Tesla's device, which they then tested on an abandoned bridge. While the structure was not reduced to rubble as predicted by its inventor, the vibrations it caused resonated much further than the MythBusters expected. Could this machine have caused the devastation Tesla claimed had he been alive to rebuild it? Probably not... but we'll never know for sure.
7) The Car Punch from Hellboy
Remember the scene in the first Hellboy movie where Hellboy stops an oncoming car by bringing his badass stone hand down on its hood, causing it to flip through the air? Sure ya do! Could it happen? Not as far as MythBusters could find out. It doesn't matter how much force you use in punching it down on its hood, a car of the type used in that scene simply won't pivot enough to flip over. They even tried to compensate for this by adding an extension to the hood, thus pushing the fulcrum back. Still didn't work. In the end, it's nothing more than an example of comic book physics in action -- scientifically absurd, but awesome to see.
6) Super Powers
This entry is something of a cheat, as it's not really an examination of a myth, and wasn't a part of an aired episode, but instead appeared on the Mythbusters website. Regardless, it's simply too nerdy to pass up. See, there was an episode which dealt with things from superhero comics and movies that could conceivably be tested and reproduced in the real world, so the matter of super powers wasn't really explored. To make up for this oversight, the gang moved the discussion to the web where Jamie and Adam focused on the feasibility of becoming a superhero by receiving the abilities of a spider, while Tori and Grant mulled over the pros and cons of gamma radiation exposure. Guess which there are more of?
