The first method uses a cooler (Styrofoam or plastic) and requires you to drill a hole on the top of the cooler. You will need to outline the circumference of the fan with a marker, making sure to make it slightly smaller so that the fan can rest on the opening without falling into the cooler. Once this is done, you will need to drill another hole for ventilation. You can use a cut our dryer vent or an elbow PVC pipe for this. The vent hole needs to be wide enough to hold either of these in place.
The next step is to fill the cooler with ice. You can use regular ice or water frozen in a container. Water frozen in plastic water bottles works well. One you replace the top of the cooler, place the fan and the elbow pipe or dryer vent in their appropriate openings. After making sure they fit snugly, it’s time to start the fan. You should now be feeling a cold breeze coming from the opening.
This method uses elements of the first, but instead of a cooler you use a 5
