Bubble machine

The Bubble Maker STEM kit is a delightful and educational tool that introduces children to the joy of exploring physical science and fluid dynamics through play. By building this kit, kids engage with the properties of liquids, the mechanics of air pressure, and the concept of surface tension, all of which play a role in bubble formation.

As the mechanism dips into the soap solution and the fan begins to blow air, children can observe how the force of the air interacts with the soapy film stretched across the bubble wand's openings. They will learn that the surface tension of the soap solution tries to minimize the surface area, which is why bubbles naturally form a spherical shape once they detach from the wand. Additionally, they will see how the fan's force must be balanced with the delicacy of the soap film to create bubbles instead of just disturbing the liquid surface.

Through experimenting with the Bubble Maker, children will also gain an understanding of how gears can transfer motion from the motor to the wand and fan, providing insight into basic mechanical engineering principles. This kit is not only educational, providing a foundation in fluid dynamics, but it's also incredibly engaging, encouraging kids to experiment with different soap solutions, fan speeds, and wand shapes to create bubbles of different sizes and longevity, thereby fostering a hands-on understanding of the scientific method.
