Seeking a Friend for the End of the World: A Bunker Full of Imposibilities

Last weekend I saw the movie: Seeking a Friend for the End of the World here’s my review sort of (spoilers to follow):

Titanium cylinder

On the other hand, with his titanium slammer, Speck would have been Pogs champion and thus ruler of their new society

Forgetting everything else and jumping ahead to roughly where the movie turns from hilarious to depressing: Keira Knightley or “Penny” decides to see an ex-boyfriend, “Spec” who happens to have a well-equipped bunker and some tiny cars.  Besides the obvious question about the wisdom of owning a “fleet” of tiny cars for the apocalypse with minimal off-road capabilities, he makes the claim that his bunker is lined with 12 inches of titanium.

Titanium is of course an incredible metal having a very good strength-to-weight ratio.  The only problem with it is that is is very hard to work with and expensive.  Generally it is used for things that need to be light but strong such as high-end bicycle or airplane parts.  It is also quite expensive at around $10/pound not factoring in the expense of working with such an exotic metal.

The event was great, and I got to meet a lot of really cool people.  I’d never been to one of these events before, but it was a lot of fun, and the variety of stuff available to check out was quite impressive.  After being on “the other side” of the table, here’s a few things that I would say were essential to having a good booth (In no particular order).

Stuff to bring:

  • Tablecloth – The tables provided are fine, but this will really make things look good.  I used a canvas painting dropcloth which worked well.
  • Extension cord – This almost got me, but you really don’t know what the outlet situation will be until you get there.  Be prepared.
  • Basic tool kit – Like an extension cord, best to be prepared.  Pliers, duct tape, Mig welder.  You know, the basics.
