Air Conditioning the Air Several Rooms Away
What do you do when you only have one air conditioner in your home but have multiple rooms? You could purchase another air conditioner, but that would mean letting Big Air Conditioner win. Do what this engineer did instead and take a long plastic bag to redirect cooled air from your AC to different parts of your home.

Granted, this doesn’t appear to be a long-term solution, but that’s not what quick engineering is about. It’s about solving a temporary problem with a temporary solution that might last a lifetime. At least plastic is pretty cheap, so fashioning another chilled-air redirecting vent isn’t out of the question.
