Necessary materials:
- a container for soap bubbles
- motor
- neck of the bottle
- neck of detergent
- crown
- switch
- connector
- thin metal
- a pen
Step 1: First we need to make a propeller. We cut out a circle from a can (the diameter should coincide with the inner diameter of the container). Then we drill five holes: one in the center, and four outsides, as shown in the photo. Then we make incisions, and bend the blades to make a propeller.
Step 2: Then we take the neck of the bottle and attach the motor to it with glue. Then we fix the propeller onto the resulting structure. And we fix all this into a container.
Step 3: Then, from the back of the container, make small holes. Next, take the neck of the detergent and glue it, as shown in the photo. Glue a small segment from the handle to the neck.
We cut out a small piece of breathable fabric, and insert it, as shown in the photo.
Step 4: Next, solder the connector to the motor.
That's all! Our mini keyboard vacuum cleaner is ready, insert the crown, and use it.
