Blowing bubbles is a game that many children love.
This bubble machine uses a slow-speed motor and a high-speed motor to drive the bubble wand and fan blades respectively. The rotating bubble wand is used to apply the bubble solution, and when it reaches in front of the small fan, colorful bubbles will be blown out!
Colorful bubble machines float up and down in the air, looking just like beautiful little butterflies. So lovely and magical, they inspire endless imagination and longing. There is so much more beauty in life—let’s create it together!

Do you know?
1. Why is the bubble colorful?
When light passes through the soap film, refraction occurs at both the top and bottom of the film. A soap film can contain approximately 150 different layers. The chaotic color mixture we see is caused by an imbalance in the layers: thicker film layers reflect red light, while thinner film layers reflect purple light, with the middle layer reflecting a spectrum of colors.
2. Why are bubbles round?
All liquids have "surface tension," which is the result of mutual attraction between liquid molecules. The molecules attract each other, and the attractive forces from within the liquid cancel out, creating "surface tension" on the surface. Due to this pulling force, the liquid surface tries to contract into a smaller area. When the volume remains constant, the spherical shape has the smallest surface area, so the surface tension resembles the shape of a bubble membrane, resulting in a spherical form.
