Bubble wrap window insulation

Did you get a lot of things in the mail over the holidays? Did it come wrapped in bubble wrap?

Reuse that bubble wrap (that hasn't been popped) for covering your windows. The insulating value comes from the small pockets of air in the bubbles. Cut the wrap to size and put over glass, over each pane.

I hear you can spray the clean glass with water, and attach the bubble wrap that way, so I will have to give it a try. Basement windows or windows that have no view are best, since the bubblewrap will obscure the view.
