TX-17 - Electric STEM Kit - Static Flying snow

Static Flying Snow (TX-17) ⭐⭐ · ~20 min

⚡ Principle Friction between the flying foam and the inner wall of the plastic cup creates static electricity. Even after the motor stops, the lightweight foam remains attracted to the walls by electrostatic force.

🔩 Parts Wooden boards + motor housing Motor ×1 + three-leaf fan ×1 Plastic cup ×1 + foam balls Knife battery box ×1 + foam glue

📋 Steps

1. Assemble the motor and its wooden housing as shown.

2. Connect the battery holder wires to the motor, then fix the assembly to the bottom plate.

3. Install the number 4 wooden circle onto the shaft.

4. Install the fan blades on the motor shaft.

5. Pour the small foam balls into the plastic cup.

6. Finally, fix the cup onto the structure and turn it on!

⚡ Fun Fact! Static electricity can reach over 3,000 volts, but it has very little current, which is why a small "zap" from a doorknob doesn't hurt you!

💚 Tip Make sure the cup is dry. Humidity is the enemy of static electricity — if it's too damp, the snow won't stick!
