"KEY POINTS
• Surface ice-melt water can migrate downward driven by the osmotic pressure associated with a cryopeg, a lens of salty water below
• Overpressure can cause the frozen soil to crack resulting in mechanical explosion.."

Progress on the laptop stand, too. Got the folding mechanism sorted out. Gave up on not using metal, because I'm running out of patience on this project and we've got some other stuff going on.
Grabbed some threaded rod and done. Then marked where the slots need to go and carved them out.
Just some glueing and coating left to do. The side table is already in the garage with two coats of woodstain on.
Oh, and plug some wrong holes 😳

For those interested in the compatibility of enactivism and mechanism, Jonny Lee has a nice new paper out on this topic.
