How do you get dry ink pens to flow?

To revive a dry ink pen, start by shaking it gently to mix the ink. Then, try scribbling on a rough surface, like paper or cardboard, to encourage the ink to flow. If that doesn't work, you can dip the tip in warm water or rubbing alcohol for a few seconds to dissolve any dried ink. Lastly, check if the pen has a removable tip; if so, you can clean it carefully before reassembling.
