Mechanical STEM Centrifugal Spin Dryer Kit

Centrifugal Spin Dryer STEM Kit

(Science Small Production: Centrifugal Force Explorer)

🌀 Key Features & Learning Value:

1. Physics of Centrifugal Force:

   • Build a functional hand-crank spin dryer demonstrating how rapid rotation forces water outward from fabrics.

   • Visualize Newton’s First Law: Objects in motion move away from the center.

2. Engineering Design:

   • Gear system optimization for efficient spinning.

   • Balanced drum construction to prevent vibrations.

   • Water-collection chamber design.

3. Real-World Application:

   • Simulates principles used in washing machines, lab centrifuges, and fruit dehydrators.

📦 Kit Includes:

• Perforated drum chamber (transparent)

• Hand-crank gear mechanism

• Water-collection tray

• Test fabrics (microfiber squares)

• Manual with experiment prompts

🎯 Skills Developed:

✅ Scientific Method: Test variables (spin speed vs. drying time).
✅ Physics Analysis: Observe centrifugal vs. centripetal forces.
✅ Troubleshooting: Balance loads for smooth operation.

⚙️ Specifications:

• Age: 9+

• Build Time: 25–35 mins

• Test Capacity: 2–3 fabric squares (5x5cm)

• Tools Needed: None (snap-fit assembly)

🔍 Real-World Connections:

• Washing machine spin cycles

• Honey extraction in beekeeping

• Medical blood sample separation

"甩干机" = Spin Dryer – a practical lesson in rotational physics!
Safety Note: Blunt parts | Splash-proof design

💡 Perfect For:

• Physics labs on rotational motion

• Engineering design challenges

• Homeschool applied science units

• Science fair demonstrations

Classroom Activities:

1. Efficiency Challenge: "Dry 3 fabric pieces in ≤1 minute."

2. Variable Testing: Crank speed vs. water removal rate.

3. Redesign Task: Modify drum holes for faster drainage.

🌟 Why Teachers Love It:

• Teaches inertia/force principles through tangible results (measurable water extraction).

• Aligns with "开发思维" (cognitive development) via problem-solving.

• Fosters "益智拼装" (intelligent assembly) with mechanical reasoning.

⚠️ Note: Not for wet clothing – demonstration fabrics only.
