Instructables from Guatemala
We investigated Mayan ruins in Tikal and Copan, climbed a volcano and stood 2 meters away from an active lava flow, learned to salsa dance, visited the Valhalla Experimental Macadamia Nut Station, were attacked by a scarlet macaw that ate one of my shirt's buttons, and ate as much typical Guatemalan food as our stomachs could hold. I liked Pepian de pollo so much, I took a class to learn how to cook it myself.
Some of the things we learned have already been posted:
Air Bags for Eggs
Create an Ergonomic Standing Desk and Office on the Go
How to Sharpen Knives
and we've got Instructables coming soon for many of the traditional dishes and how they run the macadamia nut farm.
All of our pictures can be found on this Flickr collection.
