In a magical world, butterflies secretly transformed into a whole new kind of species with tough and charming wings. They turned into the most beautiful creatures, dancing gracefully among the flowers every day. Inspired by their beauty, a creative inventor made a cool mechanical butterfly model. It’s super detailed and mimics the elegance of those evolved butterflies.

Crank and Piston Mechanism

The lifelike butterfly flight is achieved by the crank and piston mechanism (crank train). It is commonly employed in cars and has a fascinating history. Initially introduced in the late 19th century, it revolutionized transportation by converting linear motion into rotational power. 

The mechanism operates through a dynamic process. When fuel ignites within the cylinder, the piston moves up and down in a linear fashion. Connected to a crankshaft, this linear motion is transformed into rotational energy, which powers the vehicle’s wheels.

Plastic Mechanical Model

This model is mainly made of PVC and ABS which provide strong protection for the model and have high durability. More importantly, they do not contain harmful substances such as phthalates or bisphenol A (BPA).
