How to make an AC cooler with cardboard and materials.

To make an AC cooler with cardboard and materials, you will need the following items:

- Cardboard box
- Styrofoam cooler or ice packs
- Aluminum foil
- Ice or frozen water bottles
- Fan
- Utility knife
- Duct tape

Here are the steps to make an AC cooler with cardboard and materials:

1. Cut a hole in the top of the cardboard box large enough to fit the fan. Make sure the fan is securely placed in the hole.

2. Line the inside of the cardboard box with aluminum foil to help reflect the cold air.

3. Place the styrofoam cooler or ice packs inside the cardboard box. If using ice packs, make sure they are frozen before placing them in the box.

4. Fill the styrofoam cooler with ice or frozen water bottles. This will help keep the air inside the box cool.

5. Turn on the fan and place it on top of the cardboard box. The fan will help circulate the cold air inside the box.

6. Use duct tape to secure the fan in place and seal any gaps in the box to prevent cold air from escaping.

7. Turn on the fan and enjoy the cool air coming from your DIY AC cooler.

Note: This DIY AC cooler may not be as effective as a traditional air conditioner, but it can help provide some relief on hot days. Make sure to monitor the ice levels and replace them as needed to keep the air inside the box cool.

Materials:

- Cardboard box (large enough to fit a desktop fan)
- Aluminum foil
- Duct tape
- Scissors
- Ruler
- Pencil
- Desktop fan

Instructions:

1. Prepare the Cardboard Box: Cut out a large rectangle from the front of the cardboard box, big enough for the desktop fan to fit through. Cut out a matching hole on the opposite end of the box for the airflow to exit.

2. Insulate the Box: Fold and crinkle aluminum foil into large sheets. Line the inside walls and bottom of the box with the aluminum foil, securing it with duct tape. This will create a reflective barrier to keep cold air inside.

3. Create Airflow Channels: Cut two rectangles out of cardboard slightly smaller than the height and width of the box. These rectangles will create air channels to direct the airflow.

4. Assemble the Airflow Channels: Tape the first rectangle to the inside of the box behind the desktop fan, creating a channel that will guide the air upwards. Tape the second rectangle behind the fan, creating a channel that will direct the air downwards.

5. Install the Desktop Fan: Position the desktop fan facing the airflow channels and insert it through the hole in the front of the box. Secure the fan in place with duct tape.

6. Adjust and Seal: Check the airflow by turning on the fan. Adjust the position of the channels and fan if necessary to optimize airflow. Seal any gaps between the fan, channels, and box with duct tape.

7. Optional: Paint or Decorate: If desired, you can paint or decorate the cardboard box to enhance its appearance.

Tips:

- Use a larger box for better airflow.
- Choose a desktop fan with good airflow capacity.
- Seal all gaps thoroughly to prevent air leaks.
- Keep the cooler in a shaded area or avoid direct sunlight.
- If the cooler is not sufficiently cooling, consider adding an additional fan or a small ice pack inside.

Note: This AC cooler will not produce cold air like an actual air conditioner, but it can help circulate and cool the air within a small space.
