This tutorial will show how to make a water dispenser science model at home for a science exhibition.

The water dispenser is a great science experiment. Sometimes water dispensers can be essential to pouring water into a bottle or vessel.


So let us begin with our project by gathering all the required supplies to complete this science project.


  • Three cardboard (15×13)cm
  • Three cardboard (10×6) cm
  • Two cardboard (9×6)cm
  • Cover cardboard (60×20)cm
  • Plastic bottle
  • Hot glue gun
  • Straw
  • Sharp cutter

Steps To Make Water Dispenser Science Model

Step 1: Firstly, cut the cardboard into a cube shape and stick the base on one cardboard with one side curve.

Step 2: Glue the cover cardboard along with base cardboard. The second Cardboard is glued over the base cardboard to lift the bottle.

Step 3: Now make a small hole on the front side of the cardboard, through which the straw can pass.

Step 4: Make a hole on top the size of a plastic bottle, also make a straw size hole for the plastic bottle.

Step 5: Using the glue gun, attach the straw to the plastic bottle’s hole. This straw is passed on the front cover of cardboard.

Step 6: Now attach the top cardboard to the back part, and now the water dispenser science model is ready to use.

How To Make Water Dispenser Working Model For School Science Exhibition


The water dispenser is a valuable device that can be made easily at our house. In a water dispenser, the central concept is gravity and pressure.

Also, when we open the bottle’s cap, water flows through the straw, and when we close its lid, water stops flowing. When we open the bottle’s lid, a plastic bottle’s size, air starts to press the water, and water flows via a straw. And when we close the lid, pressure is absent as a result; water stops flowing.

Things To Remember

  • Carefully use a hot glue gun; it may burn your hands.
  • Properly handled knife or cutter; it may cut.
  • Working slowly and carefully with the battery and water.
  • Learn all you can about the materials and techniques you’re using.
  • Be careful while attaching wires.
  • Work on a self-healing mat to protect your work surface.
