Every one of us knows the problem: You are planning your project on a whiteboard and suddenly the Sharpie doesn't want to paint anymore. Well, what we do next is that we throw that poor Sharpie frustrated and as hard as possible in the direction of a trashcan. But what if we would have used that kinetic energy to refresh the marker and still release our frustration about the marker? Well, this is what this project does! Take the unusable Sharpie and put it into the construction. Next, just spin it around a couple of times and voilà there is your old Sharpie but good as new.
Attention: make sure that you don't spin it too hard, else Sharpie is probably going to vomit (yes, I'm serious). Also hold the string tight for that you won't shot the good old Sharpie unintentionally out of the window.
