Tool Trick: getting more mileage out of markers

If your magic marker is running dry, tape a string to the bottom of it and spin it over your head in a big circle. A few times around will generate enough centrifugal force to push any remaining ink to the tip.

Warning: There is usually a lot more ink left in a "dry" marker, so make sure the lid is on security before you start and remove it carefully when you are finished.
