Given the choice of anywhere to live, I'd have to put this cotton candy house near the top of my list.
Unfortunately, the house is not made entirely out of cotton candy, as I imagine the sweet treat doesn't make for very durable load-bearing structures. Instead, the cotton candy house is made out of wood, while the insulation on the inside is made out of the popular amusement park treat.
The inside of the house made by Jennifer Rubell looks a lot like a padded cell, which is not a bad environment to be in if you ingest that much sugar in one go. The project needed 1,800 cones worth of cotton candy to complete, which is actually not bad when you consider that it's acting as insulation for an entire room.
Let this project be a lesson; partially edible domiciles are better than non-edible houses.
