They say that TV is bad for you. That's not entirely true. Catch It/Keep It is bad for TV... a 50-in plasma HDTV, to be exact. And on the season finale, a high-def set will leave a hi-def crater in the ground unless tonight's challengers can stop it at the source.

Tonight's Challengers...

- LENNON RODGERS, team engineer, he has a Masters from MIT, and his brain is his ultimate weapon.
- JOE ALTIERI, team carpenter, he designs homes and is a general contractor and foreman.
- MARTY HINTZ, team metal fabricator. When this elevator constructor is not welding sparks, he's throwing'em.

The challenge... stop a TV from falling 55 feet onto a bed of steel spikes.  You're not allowed to interfere with the spikes or the crane. Oh, and did we mention that it will be suspended via twine that is set to burn off thanks to a blowtorch?

And like it or not, prepared or not, the drop is happening in 48 hours.

After the first hour, they decide amongst balloon, slides, a trapeze, and a bounce house. Lots of good ideas, but what will be part of the final build? It's going to be... a pulley system guided by two 50-foot aluminum towers and sheer man power. They need to be able to stand the whole thing up by themselves. The only thing that they may have to contend with is the sheer magnitude of this build.

29 HOURS REMAINING

Lennon's getting a jump on things to start day 2. If they can get the pieces they need today, they'll be golden. Meanwhile, Marty is still MIA. At 10:30a, Sleeping Beauty finally makes an appearance.

Joe volunteers to go to IMS to pick up the remaining materials he needs to finish the build. Back at the shop, Mike is beefing up his flame. He only had one torch in the demo. He's working on three more. He's looking to burn more than just the twine. He wants to burn the crate, the ropes, the TV, everything.

Lennon is working on the anchor systems for the pulley.

With half of the time gone, there's a lot of talk, but not a lot of building.

TEST #1: Mike's Weight Simulation Test. The team will test whether or not they can actually handle 200 pounds of TV and case. Marty is going to have to play anchorman to have a chance.

21 HOURS REMAINING.

Troubles begin to arise on the team as they're scrambling to build their truss. Marty's building his crate to protect the TV from the cranes. Joe makes a discovery... the box is messed up. They have to extend the top and bottom.

TEST #2: Mike's Heat Resistance Test. Mike's torches are 2100 degrees. If their crate isn't properly insulated, then their TV is going to fry before it hits the ground. He's been gracious enough to supply an old toilet. And then smash it after a minute and a half.

17 HOURS REMAINING

The team gets back to work building and securing. Everything is coming into place. Meanwhile, Zach & Mike drop stuff for science. Turns out that at 55 feet, you're looking at a fall of 1.849 seconds, no matter what you drop.

Inside, the team has its truss close to its final height, but it is so long right now that it's bending and close to buckling. If it's hoisted into the air, it's not going to hold itself up let alone a TV. They add wood reinforcements, but that adds a lot of weight. Lennon is worried that the height will not clear the undercarriage of the crane. The crane itself is 56.5 feet in the air, while the poles are an even 60 feet. So they're going to have to cut it down to size.

Meanwhile, the box is not yet ready... and Marty's asleep. Again.

TEST #3: Mike's Spike Impact Test. Mike's built a pneumatic spike to simulate the effects of gravity and impact. He shoots it at a mock-up of the case. And cue kill stabbity death. The team thinks that they're going to prevent that from happening.

10 HOURS REMAINING

Did we mention that Mike's STILL working on his flame?

Marty's still working on the box while Joe and Lenny are working on the truss. Mike notices that the box and truss are still "Plan A" with no "Plan B". And the spray adhesive used to adhere the aluminum foil to the box... is very flammable.

And Marty has to puke. Catch It Keep It? He caught something... Dysentery.

The guys use foam to insulate the box and 2x4s to weigh down the truss.

3 HOURS REMAINING

Marty's nowhere to be found while the other two put the finishing touches on their build. Without Marty, they boys might not have the strength to lower the TV on their own.

Thirty minutes later, Marty arrives ... and finally finishes the box.

1 HOUR REMAINING

The boys will drill into the ground to secure their guide wires.

20 MINUTES REMAINING

The team tries to move their truss into position. The crew has to step in and help them move it out of the shop and into the ground.

EIGHT MINUTES REMAINING

Joe's truck is going to be used to raise the truss into position.

Mike moves his Dragon's Breath and the TV into position.

Joe puts his truck into drive when all of a sudden... at 7 minutes to go, the iron bar suspending the TV bends. Now according to the rules of "Catch It/Keep It", you cannot mess with or otherwise alter the method of destruction. In using the truck to raise the rig, however accidentally, they did... so it's a loss.... for now.

BUT there's a slim chance that it'll survive a drop in that box. Let's find out in five... four... three... two... one... FIRE! The foil's working for a bit when it starts to flake off...

The drop... lands between every spike. It's a miracle. Unfortunately, the screen split, so ... it's a loss.

For the record: Mike's solution would've involved making a giant insulated metal wedge that would've held the TV in place AND severed the spikes on the drop. But as the show ends, it's just a theory on a chalkboard.

And that's it for Catch It/Keep It season 1. Will we see a season 2? That's for Science Channel to decide. In the meantime, remember this... if you catch it, you keep it.
