Wood shrinkage

This is a delightfully retro video looking at the microstructure of pine wood and why it shrinks when it dries. It gets quite complicated with the terminology but has good visuals that help show how things work even if you don't understand the words. The things that look like air bubbles are meant to represent water droplets.

You might also want to look at our video about the chemistry of wood (on the firrs webpage).
