In this tutorial, we will show you how to build a mini air cooler science model for a school science exhibition at home by using material that is readily available at home.

This mini cooler works with a battery, ice cubes, and bottles, which is economically and environmentally friendly. It blows the air from the top towards the ice cube then more relaxed air exits from the outlet of the cooler.


To build a mini air cooler science model, we need :


  • Small Fan
  • DC motor
  • Battery
  • Wires
  • Hot glue gun
  • Scissor
  • Box cutter


  • Small plastic bottle
  • Large plastic jar
  • White paper
  • Sketch pen
  • Waste boxes

Steps To Make An Air Cooler Model

Step 1: First, take a large jar and cut the upper lid with the help of a box cutter to equal the size of the DC motor.

Step 2: Then, mark the upper lid with a marker with the pattern (as given in the picture).

Step 3: Now, make a hole on the marker spot with soldering iron.

Step 8: Now add ice cubes inside Jar ( can be used dry ice for better results ).

Step 9: Now, to test your mini cooler, on the switch you’ll observe the cool air coming out through the plastic bottle.

Air Cooler Working Model For School Science Exhibition Project

That’s our mini cooler ready to represent in the school science exhibition.


The air cooler working model helps students learn how the air cooler works and how it can be built by using material that is readily available at home at a low cost.

Things To Remember

  • Working slowly and carefully during cutover.
  • Work on a self-healing board to protect your work surface.
  • Learn all you can about the materials and techniques you’re using.
  • Work carefully during wire attachment.
  • The battery will be warm during the experiment, be careful with it.
  • Be careful during work with soldering iron.
