Mythbusters Imploding Tanker Car! Tonight!

I saw this episode the other night. It's very interesting that a tank car can take such extreme pressure conditions and not implode. They had to damage the geometry of the tank car by dropping some weight on it and causing a crease in it. Also they capped or took out the safety pressure valves and replaced them with stoppers, so this was an extreme pressure test, very unlikely to happen in real life but is possible only under adverse conditions and human neglect thrown in.

But what about that imploding tank car vid they made in Europe.  I think there was a thread about it here on this Forum.

what about filling it with steam thru one of the plug holes could we get it to return to original

That would be HUGELY dangerous. Far better to fill it with pressurized water, and SLOWLY hydraulic it back into some sort of shape.

You mean this one?

(I tried embedding it, but it came up with an error.)

I suspect the car's structural integrity has already been compromised.  It's not a balloon, it would make no sense try to "blow it back up."

Any more dangerous than these?

Come on, it's Mythbusters for crying out loud.

You can see that with your plastic water bottles when you fly.  Just empty one at cruise altitude and then seal the top and wait for landing.

In the "Try this at home" category, you can take an empty plastic water bottle at room temperature, seal it, and put it in the freezer and get a similar result.

Happens all the time when I freeze half-bottles of water. The air shrinkage is significant given that the water expands when it freezes.

Where can I find this online to view?
