Whistling with a Turbine: A STEM Experiment What happens when you add a turbine to an existing whistle? Will it still make the same sound? The answer is not straightforward. Adding a turbine with variable blades changes everything. It's no longer a whistle, but rather an intriguing instrument that produces unique sounds. The design of this project showcases STEM connections in action. To create a whistle, you need three essential components: a body, a turbine, and a snap-on cover. Lubricating the inside of the turbine can enhance its spinning performance, while superglue ensures a permanent assembly. Files Included: Three distinct bodies are available for experimentation: 1. One with a 7mm opening 2. Another without an opening 3. A curved airway design All three use the same cover. 2. Turbines with varying numbers of blades to explore different sound patterns 2. Two covers, including one that is slightly tighter, allowing for more precise adjustments A regular whistle serves as a reference point (5mm opening) without a ball in it
