you can bend/compress wood with steam. But look at the width of that bottle neck.
The others I looked at (playing cards, rubicks cube, ...) can be disassembled in smaller pieces that go through. That's his technique. So how do you disassemble a plank? I think it's a hollow piece of thin plywood (1 piece, no seams) that was soaked, folded up and then filled with something (resin).

Or the wood is soft and compressible when wet, but returns to its original shape when it dries.
Some woods (including pine) are much more compressible than you might expect: http://www.ewpa.com/Archive/2006/aug/Paper_306.pdf
My favorite example of this is the "nail in wood block trick."
