Science Experiment: Is Black Really Just Black?

Today we had a fun experiment to answer the question, "Is black really just black?"   To discover the answer to this question, we drew five black dots on a paper towel. Then, we stuck a pipe cleaner through the middle black dot and placed the pipe cleaner into a cup filled halfway with water.  After waiting for a few minutes, we found the answer to our question.  The water travels up the pipe cleaner and when it touches the black marker, the black starts to spread and reveals many different colors!!
