Did you know that the tip of a pencil can exceed 200°C using only a battery? In this video I show you an interesting experiment on how graphite can conduct electricity and generate enough heat to melt tin, creating a small DIY soldering iron.

🔧 How does it work?
✔️ The graphite in the pencil is a great conductor and, with the right voltage, can heat up quickly.
✔️ It can melt tin, but it is only a demonstration test, not a method recommended for everyone.

⚠️ Note: This video is for demonstration purposes only and shows a simple science experiment.
