A flaming guitar. A flaming pile of thermite. Three flaming musicians/engineers. An open flame. Things are about to get white hot!

Here's a comparison... A candle will burn at 1400 degrees. Firepit... 2000. A flamethrower... 3000. But the MOD today burns at 4500 degrees. It's called... thermite. Thermite is a compound of aluminum oxides and iron that, when ignited, burns so violently that it will burn through almost anything. Including.... a $2000 Gibson Les Paul guitar, the tastiest guitar ever made. And if the challengers want one, they'll have to save it.

- Christopher Dow, aka DOCTOR WOOD. He's a drummer and a custom carpenter... and a badass... Nuff said.
- BRUCE WAYNE ECKELMAN, inventor and guitarist
- JOE TESSITORE, a fabricator who once chopped a Ducati muscle bike.

Their weapon... 100 pounds of thermite. Unstoppable when ignited, and burns hot and quickly until there's nothing left but molten slag. They have 48 hours to save a Les Paul from all that molten lava. They have an hour to come up with a plan to save that guitar. They cannot touch it or the MOD until the 48 hours are elapsed.

Time... starts NOW.

And two-thirds of the team get a running start. Wood wants to order some fire-retardant plywood and drywall to make a box. Joe suggests a support for said box. Bruce also wants a cooling agent. Wood doesn't want the cooling agent. In the end, they're going to go the multi-layered box route. But Mike suggests that they're going to turn the box into a giant furnace. He thinks that a cooling agent would be a good idea.

Meanwhile, Team Metal can't cut and weld metal, while Wood takes another look at the guitar. The fire is just going to shoot up the pipe. He makes a slit to accommodate the armature of the rig.

TEST #1: Material Resistance. A VW Bug is supported by aluminum, steel, and wood pillars. On the bottom... ignited piles of thermite. The wood withholds, while the steel and aluminum melts. Wood will withstand the heat better than metal. The plan is not altered.

Team Metal's frame is starting to come together.  Zach arrives and tells the team that Mike is working on his own solution. His solution: evacuation. A tower with an arm that will yank the guitar via pulley.

Wood is building his box. He's feeling good about the rig. The first day is always weird, but with 34 hours to go, Wood calls it a day.

22 HOURS REMAINING

Wood starts lining his box with drywall, when Bruce had an epiphany... a Shop-Vac with ice on blow through a pipe to cool the box. Basically, an air conditioning system. Wood doesn't want to put a hole through his box. Joe says that they're going to put the hole in it anyway. But first, they decide to add on a steel roof to the box.

Bruce is convinced that they have a team of two. If Wood wants to join in, good job. But he's got a team.

Zach has his own solution... which requires stunt-man-type acrobatics and a convertible.

The team moves forward with the original plan, trying to mount the box around the guitar. They manage to assemble their creation in its place... when Zach arrives with...

TEST #2: Radiant Heat. A Les Paul in the box will be subjected to a lot of heat. Using a sheetmetal box, the team will figure out how hot the rig can be until things start to go terribly wrong using a sample guitar. And we have smoke and fire at 131 degrees. That is a drop in the bucket compared to the 4500 degrees that thermite will produce. This will add weight to the argument that they need a cooling agent.

"The heat is on..." Glenn Frey.

Wood is still fine tuning his box, while Bruce and Joe are still trying to hem and haw their way around a cooling system. They think that they have Wood worn down. In the end, the cooling system goes in. Test run goes off without a hitch. They're golden.

Meanwhile, Mike's solution is finished as well. He tests it on a test guitar... and it works.

17 HOURS REMAINING

... and Dr. Wood is calling it a day again. It looks like he's quite justified as the team goes into some finishing touches, including having Mike test the drywall.

It doesn't end well. It went with a hole in the bucket.

6 HOURS REMAINING

Everyone's well-rested, and it's time to finish it up with a few fail-safe measures, including a drywall wall between the rig and the Shop-Vac AND extending the amount of pipe between them... all while waiting for Dr. Wood to show up.

Little less than three hours to go, and Wood shows up fashionably late. Meanwhile, Bruce fabricates a shield out of metal to deflect the slag.

30 MINUTES REMAINING

The metal roof is in place, and now it's time to power on the Shop-Vac, but first... the test. And the freezing air and the humidity chokes the motor. The question is.. will it be enough to save the guitar?

Time to make it rain fire in five... four... three... two... one... BURN, BABY, BURN!

And after it rains flames, the box is still there, but is the guitar still in one piece? Remember, it's only a catch if it is in MINT condition. And... it is! Zach calls it a CATCH!

But how did Mike's rig do? It... didn't. Apparently the thermite snapped more than just the roof.

Well, that's another prize caught and another prize kept. Will we have another win next time? Remember, if they catch it, they keep it.
