STEM
The window in the living room is stuck open during the rain storm. This is a little detail but the science behind it is pretty neat. Because wood is a porous material, it will absorb liquid. In the case of the rain storm, the wood absorbed the moisture in the air as well as the rain hitting it. That caused the wood to swell, just like a kitchen sponge swells with you get it wet.

I've always wondered how and why wood cups and curves and bows as a it dries. In looking at the resources below, I now have a better idea. As for the swollen wood in this episode, that's pretty easy for me to understand. Being a fan of home improvement shows, I know that there needs to be some room for expansion and contraction when it comes to certain wood working projects.
