Also, one is pretty and one is pencil lead.

另外，一个很漂亮， 一个是铅笔芯。

But it's just carbon, the same element that makes up the graphite in this pencil lead, which is so soft, that it's intended purpose is to rub off on stuff.

但它只是碳， 与构成这支铅笔芯中的石墨的元素相同，它非常柔软， 其预期用途是擦掉东西。

Graphene, which consists of monolayers of carbon atoms bonded in a repeating hexagonal pattern, can be made in a number of ways, mostly by stripping flakes of carbon from mined graphite (sticky tape and pencil lead will do).

石墨烯由以重复的六边形图案结合的单层碳原子组成，可以通过多种方式制成， 主要是通过从开采的石墨中剥离碳薄片（胶带和铅笔芯即可）。
