Make Bubble Machine for Kid From Cardboard

Bubble machine is a toy that children love. Besides manual machines, there are now many electric models.

Today I tried to make a bubble machine from cardboard.

- Cardboard:

Find at your home :)

Step 1: Create a Motor Stand

Use cardboard, glue, and candle glue to connect the components together.

Step 2: Create a Soap Dish

Basically, the principle of operation of this dish is that it will spin, and half of this dish will be submerged in soapy water. When spinning, soap will stick to the small holes in the plate.

Step 3: Create a Soapy Water Container

This box will contain soapy water, and on top is a rotating disk.

Step 4: Electrical Circuit

The circuit diagram is relatively simple, with 2 DC motors: One motor for the rotating disc and one motor for the blower blade.

Step 5: Finish & Testing

Connect the power to the 18650 battery. Then put soapy water in the box and test the results.

The soap is not too much, but I think it can still be improved by optimizing the airflow, fan blades...

Thanks & hope you enjoy!
