Motorized Ball Launcher - DIY STEM Kit

🚀 Motorized Ball Launcher Kit (Age 8+)

High-velocity physics. Launch, learn, and calibrate.

⚡ A hands-on electrical and mechanical assembly kit that teaches kids the fundamentals of kinetic energy, friction, and motorized propulsion using a high-speed DC motor and spinning launcher wheel. 🎯

❓ Why parents will buy:

An interactive building project that introduces children to electronics and mechanics. Perfect for science fairs, classroom experiments, and testing projectile trajectories with safe ping-pong balls.

📚 What kids learn (fast):

Rotational kinetic energy, friction-based propulsion, electrical circuits, motor speed control, and projectile trajectory angles.

🔑 Key features:

✅ 3D-printed, snap-fit structure (no glue needed) — robust and easy to assemble.

✅ High-speed DC motor and rubber-grip launcher wheel for consistent, rapid firing.

✅ Manual crank adjustment system to easily calibrate launch angles and trajectories.

📦 Kit contents:

3D-printed structure components, high-speed DC motor, battery container, rubber-grip launcher wheel, manual crank assembly, ping-pong balls, target accessories, activity manual, and instructional video guide.

❤️‍🩹 Safety & support:

Uses lightweight ping-pong balls for safe indoor/outdoor launches. Recommended adult supervision during initial motor wire connection.
