If you’ve got kids, this is bound to happen: dried out markers end up being tossed into the trash. Before tossing them out, try soaking them in warm water. Just remove the caps and place the felt tip part of the marker submerged in warm water in a cup for about two hours. Remove the marker and try it on paper; it should be revived and rehydrated. If not, soak for another two hours. This trick also works for highlighters.
