Whistles with a Turbine, STEM Play

Whistles Whirl with Turbines, STEM Play This project takes the concept of a previous whistle project to new heights. What if one were to add a turbine, equipped with a varying number of blades, to an existing whistle? The result is certainly not a traditional whistle, but it still produces some fascinating sounds. Overall, this design project effectively demonstrates STEM connections in action. To create a whistle, one requires a body, a turbine, and a snap-on cover. Adding a touch of lubricant to the inside of the turbine can enhance spinning performance. For a permanent assembly, a small amount of superglue may come in handy. Among the files included: 1. Three distinct bodies: one featuring a 7mm opening; another with no opening at all; and yet another with a curved airway design. They all utilize the same cover. 2. Turbines with varying numbers of blades are also available for experimentation. 3. Two covers, including one that fits slightly tighter than the others. 4. A regular whistle is included as a reference point, featuring a 5mm opening and no ball inside.
