    I found THIS link on an astronomy board I go on. I bet you would have problems modeling that car! :p

    1) Buy tanker
    2) Apply foot

    :D :D :D

    1. Buy tanker
    2. place in oven and heat until plastic is soft
    3. Grasp firmily with tongs or pliers around the middle of the tank and remove from oven.:eek::eek:

    Wow, that must have been some serious vacuum going on there. A stuck or blocked valve or something

    A quick demo...

    ...is to take an empty 2 liter soda bottle- plastic only!!! Run some hot water in it, then pour it out- twist the cap back on. Place the warm container in your freezer and about 30 seconds later you'll probably hear a "pop". It's the sound of the plastic bottle collapsing as the warm plastic cools off- thermal expansion and contraction.

    Mark :cool:

    P.S. Make sure you put the roast for Sunday dinner back in the freezer after you remove your nicely compacted 2 liter bottle.

    You are right, just simply physics. The steam displace an equal volume of air (plus any air left inside expanded because it was heated) and maintained the same pressure as outside. When they closed all the valves, as the story says, they created an air-tight container, then as the steam cooled it turned to water and the air condensed both now displacing less volume. The resulting vacuum caused a lot more pressure from outside, more than the tank could handle. I think any valves are designed to relieve high inside pressure, not a vacuum as this was.

    I found one similar to that near me!!! Here is mine.

    Remember, we are running a "double-double" this time and this photo qualifies.:thumb::thumb: To be sure, you can enter up to two photos (separate posts though) of anything that is RR related (prototype or otherwise) and the contest runs through the end of August.

    Just thought I'd remind all those folks that haven't entered...:wave::wave::wave::wave:

    tsk tsk! You're supposed to squeeze from the end of the tube, not the middle! :)

    That tank car in seanm's post looks brand new. Almost right out of the builder's shop.

    Could you imagine standing there when it collapsed. What kind of noise does that make?

    This reminds me of what happened to a brand new tanker truck in Lynden Wa. The son of the guy that owns the dairy went to the farms in the country and collected milk. When he got back to the dairy, he connected up the lines to pump the milk out and started the pump running. He took off for a coffee break When he came back??? You guessed it. The brand new tanker collapsed like a coke can. Up until that moment, the guys father was real proud of his new truck. This happened back in the early 50's

    Frankly I was shocked to see that tanker when I got the shot. I sort of blinked a few times and thought.... Wow! Not even a paint chip on it and it done for!

    Too bad about the horizon. I guess I could rotate it a buit and crop.

    Can anybody say Pressure Equalization Valves? :D :D :D
    Same thing in reverse. Empty tank car from up in the Rocky Mountains on a cold day. Sealed and sent to (pick your favorite desert hotspot, lower elevations are preferable. Any RR in Death Valley?) Car is painted black of course. :D :D

    Oh Oh :eek: :eek: I just realized a new terrorist threat! Be sure to keep this idea to yourselves. :D :D :D :D

    There are no "Shameless Plugs", just Golden Opportunities.:thumb::thumb: As PR man for the photo contests, one takes every advantage when they come up. That's why I get paid those big bucks..:rolleyes::rolleyes::rolleyes::rolleyes:

    I was just thinking of how neat it would be to have one on a siding of your layout. A good use for the bad running/badly modeled tank car I guess.
