How To Make A Air Bubble Machine Working Model for Science Exhibition


In this topic, we are going to show you how to build an air bubble machine working model for your science project or exhibitions.

Making a bubble machine is an easy and fun project. It can be made from simple readily available material which will make toddler and kids amused and happy for hours.

With fan and motor, a bubble machine is a very easy electronic project.

This is a great project to do with scraps and odd ends hacked together. It need not look amazing however it just has to work.

how to make the bubble machine

Let talk about the main components of bubble machine science experiments which are depicted below.


It is used to hold bubble solution.

Bubble ring:

Multiple rings of holes attached to look like a fan which will spin through trough picking up the bubble solution.

Once it comes out of tough there is a small blower that blows air which helps to form the bubbles.


Motion is created using a slow moving motor to spin the bubble ring.


A small fan will force bubble liquid out of holes in the bubble ring.


Power source for the motors.

Step By Step of making Bubble Machine – DIY

First take a transparent pipe and cut it into small pieces to form rings.

Then create almost one inch small pipes by cutting straws the glue the rings to the straws.

Take a bottle cap with a central hole, pass a pen refill through it, and to this glue all the created rings to form a ring-like structure.

Attach the bubble ring to a motor. Take the trough and make a rectangle shape hole into it.

Keep scale on the trough and glue a motor to the central area of the scale. Connect the motor to wires, and check it is working properly by connecting it to the power supply.

Now mount another motor on the right end of the scale and attach a small fan to it then connect it to the power supply to check it is working properly.

Fill in the trough with bubble solution. Connect both the motors to the power supply.

Once the current starts to flow, one motor with a fan will rotate and another motor with a bubble ring with also start to rotate through the bubble solution.

As the rings come in contact with the rotating fan they become bubbles and float in the air. Hence lots of bubbles will be generated through this bubble machine experiment.

Questions & Answers on Bubble Machine working model

1. What is bubble machine?

Bubble machine basically helps to generate bubbles continuously and it can be activated and deactivated via wire.

2. What is the principle of bubble machine?

Principle of bubble machine is double needle.

3. How does a bubble machine work?

Fan helps to generate continuous air stream which helps is in a constant flow of bubbles.

4. How does blowing bubbles help children’s development?

Walking, Crawling, climbing and reaching and trying to catch and pop the bubbles help toddlers strengthen muscles and develop gross motor skills.


Bubble machine model helps to learn how to generate bubbles using simple scrap things available at home.
