    La mina de lápiz contiene grafito , una forma del carbono con una gran resistencia a la temperatura y moderadamente conductora. En el video, se utiliza la corriente de una batería para elevar su temperatura hasta que se pone al blanco. El aumento de temperatura se concentra en el grafito al ofrecer más resistencia eléctrica que los cables.
