If you thought the pencil reached the pinnacle of its evolution, think again. Sharpie has reinvented it in the form of a liquid pencil that becomes permanent after 3 days. So it’s kind of like the opposite of an erasable pen.
Apparently, the liquid graphite lays down smooth like a pen, but only turns to ink after a 3 day period. So, up until that point, it can be erased.
If people still wrote things down manually, this would be totally awesome.
