Flapping Butterfly Engineering Kit

The Flapping Butterfly Engineering Kit lets you build a mechanical butterfly and see how gears and linkages turn motor power into a lifelike flapping motion. Once it is assembled, turn the control knob to power the butterfly and adjust how fast its wings flap.

Key features

• Gears and linkages convert motor power into flapping motion
• Control knob starts the butterfly and adjusts flapping speed
• Natural wood finish
• Leave it plain or paint and decorate the wings

Following the motion from the motor through the gears and into the wings is a great way to understand how mechanisms work. Painting is optional, so the finished butterfly can be a clean wooden showpiece or a colorful decoration for a desk, shelf or bedroom. A satisfying mix of engineering and creativity.
