⚡ Cotton Gun (Mini Coil Launcher)

This project is a simple Cotton Gun powered by a 18650 battery. It works by using a coil that heats up when powered, igniting a small amount of cotton flash. The quick combustion creates a harmless burst that shoots the cotton forward — similar to a Harry Potter magic wand ✨.

The system is safe because the power and temperature are carefully controlled, producing only a small visual effect without any dangerous explosion or flame. It’s designed for educational demonstrations, physics experiments, and fun visual effects.

Features:

• Powered by a rechargeable 18650 battery

• Coil-based heating system

• Uses cotton flash for visual firing effect

• Compact and easy-to-build design

• Safe for small experiments (with supervision)
