  1. They are fun! There are a lot of different techniques, and some are even easier, but I like this way.

    Here are quick instructions in case the link doesn’t work: Fill a cup or other container with water. Cut a strip of paper towel. Put a drop of ink about one inch from the bottom of the paper towel strip. Hold the paper towel strip so that its very bottom edge is just touching the water in the container. Don’t dunk the ink in the water, though. As the water travels up the paper towel strip, the ink dyes separate out. When you see that the paper towel isn’t absorbing any more water, remove it and hang the paper towel strip to dry.
