Sharpie Liquid Pencil when we first heard about it -- it uses liquid graphite to write like a pen, erase like a pencil, and (supposedly) dry like a permanent marker after three days. Well, it's been just over a week since our first hands-on, and we've got some bad news: we can still erase what we've written pretty easily. If you squint just right it sort of looks like it might have dried a little darker, but it's certainly not Sharpie-level permanence. Sad faces all around. We've followed up with Sharpie to see what's going on and we'll let you know what we hear, but check the video after the break in the meantime.
