Is your air conditioner broken or just doesn't exist? We've got good news: it's possible to build your own air conditioning unit. These bad boys won't be as good as your industrial-grade air conditioners, but they'll make do in desperate situations. Take a 5-gallon-bucket (with a lid), puncture a hole on the top big enough to fit the front of a fan, and then drill holes around the bucket to let the airflow in and out.
Line the bucket with some netting or mesh, place ice inside of the bucket and cover it with the lid and fan. Turn the fan on, and voilà!
