How do you make a bullet pencil?

To make a bullet pencil, you need a bullet casing (typically a spent cartridge), a pencil lead insert, and a means to secure the lead inside the casing. Start by carefully removing the primer and gunpowder from the bullet casing for safety. Then, insert the pencil lead into the casing, ensuring it's snug, and seal the open end with a cap or a small piece of rubber or cork to hold the lead in place. Finally, sharpen the lead using a pencil sharpener or a knife to create a usable point.
