Go inside the volcano with national geographic:

In Disaster Lab: Into the Tornado, Tim’s next challenge is to study the interior and immediate exterior of a tornado by getting inside the storm itself. On the inside, specially designed, 85-pound probes outfitted with seven tiny cameras capture images of the tornado passing directly overhead. Added sensors measure conditions never documented before, such as temperature, humidity and wind speeds. Just outside the reach of the tornado, mesonet devises, or delicate, car-mounted weather stations, take wind speed and barometric pressure measurements.

The two teams made one of wood and one of metal. After months of debating precision cuts, the crew finds out once and for all how accurate parts must be built in order for daVinci’s inventions to work.

If you know anything about the work of Leonardo da Vinci’s you know that his self-propelled car, was a wooden three wheeled cart.

The long hours and vicious hazing begin to test the Greenhorns, and even some start to crack. On the Wizard, the rookie fights to maintain dignity as the deckboss shreds him to the core.Watch the 7 minute video from last weeks episode as they battle it out.

On tonight’s episode, the crab pots continue to come up empty and the skippers are out of ideas. Low bait and long grinds take our crews to dark places — the smallest infractions from a Greenhorn or
fellow Deckhand cause tempers and even violence to flare. Aboard the Cornelia Marie the brothers Harris have a war of words.

On the Wizard, low bait forces Keith to turn his back on his brother and reach out to an old enemy: Sig Hansen. While the rest of the fleet fight it out amongst themselves — it’s a wild, swinging pot that could do fatal damage on the Time Bandit.

Last time I showed the fish bite tradition clip. There are many other traditions including the burn barrel tradition. The Catch captains head to the “Burn Barrel,” a pre-crabbing season tradition to wish each other good luck and full pots for the upcoming season and set some stuff on fire too!

In tonight’s episode it’s week four of King Crab Season. Seven souls have perished, but the fishermen soldier on, in the hunt for crab. When Wizard greenhorn Josh decides his bait cutting post is the perfect place to pin up picture of his girlfriend, its open warfare with veteran crewmate Monte, who engages in some heavy duty hazing to convince the rookie that this ain’t no junior high school locker. Meanwhile, the Cornelia Marie struggles to hit its stride with a continuing slump in its crab count so far and now to make matters worse there’s trouble in the engine room. Over on the Northwestern, greenhorn Jake has his inaugural turn operating the hydro lift but when things go awry, Sig has to step in.

The crew of the Time Bandit is hoping to strike gold twice, trying their luck a second time in last year’s crabbing hotspot.

Discovery Channel’s six-part world premiere original series, DOING DAVINCI, puts a team of 21st century builders, engineers and historians together to take on one of history’s greatest minds as they attempt to build DaVinci’s weapons once and for all. The series airsMondays at 10PM ET/PT

Tonight’s episode title: Multi-cannon Machine Gun
In the episode airing tonight, the team will take a shot at building a multi-cannon machine gun. Everyone is on high alert throughout the build as they work with hazardous black powder, an unstable substance that could detonate on its own.

Watch below as the team builds DaVinci’s multi cannon tank

Watch more from the design of the armored tank as they try to devise which type of wheels to use for the armored tank so that it actually moves.

So you guys submitted your best YouTube myths and the MythBusters listened! Tune-in TONIGHT to find out if your submitted myths were BUSTED, PLAUSIBLE or CONFIRMED!

The MYTHBUSTERS special marks Discovery Channel’s first program partnership initiative with YouTube. Discovery aired a series of spots beginning in September 2008, hosted by MYTHBUSTERS’ Adam Savage and Jamie Hyneman, that invited viewers to become a part of the myth-busting crew by posting their favorite viral videos to YouTube.

Over 200 videos were submitted along with several thousand comments to the MythBusters YouTube channel (www.youtube.com/view_play_list?p=290018A7BF3DC8FB).

For the MYTHBUSTERS YouTube Special, Adam and Jamie test if 30,000 match heads, a tin bucket and a slow burning fuse could create a huge fireball. Meanwhile, the Build Team take on an immensely popular viral video that features a giant ball of Lego rolling down the streets of San Francisco. In one of the team’s biggest builds ever, the Build Team attempt to replicate the Lego sphere — 7-feet in diameter and purportedly created from 5 million pieces — and roll it down a hill, Indiana Jones style, into a parked car without doing any damage to the car. Finally, Adam and Jamie use a series of tests with a flexed-up muscle car to test a YouTube posting that says you can make a car tire catch fire if you spin it fast enough and long enough.

On tonight’s episode of Deadliest Catch, the boats have encountered low crab numbers which has been creating even more tension among the crew. When the fleet wakes up to ominous red dawn skies, the captains speculate that a severe storm is on the way. But with crab quota to catch, the boats keep fishing.

The Time Bandit hits pay dirt, while the Cornelia Marie strikes out. When 20-foot seas and high winds kick up — even the bravest skippers call in their men to wait out the storm. One boat, with 11 souls on board, sends out a Mayday.

In an all too familiar scene, the Coast Guard launches rescue helicopters, and the skippers stay glued to their radios — anxiously awaiting news of the fate of their fellow fishermen.

In last weeks episode “Everything on the Line” the captains are under huge financial pressure from costly summer boat repairs. Watch below as Keith Colburn gets battered and bruised while taking an exploratory dive under the Wizard’s hull.

Over with Sig Hansen he gets the short end of the stick and keeps an old fishing tradition alive by taking a big bite out of a herring.
