Katy Arillaga built her first milk jug igloo on her elementary class’ rug. She built a version of this recyclable structure to Makre Faire Bay Area 2011. The first two layers contain water and provide stability to the rest of the structure, and is built upon using layers of fewer jugs until completed. Watch more videos from Maker Faire Bay Area.
