Alternate Use for an Aquadoodle Pen

My son had an Aquadoodle set, but one day when I wasn’t paying attention he took crayons and markers to the Aquadoodle paper. I was unable to repair the paper and when I discarded it, I almost tossed the pen too but then I had an idea: I filled up the pen with water and encouraged my son to try  it on colored construction paper. It works quite well and it doesn’t matter if  my son decides to take crayon and marker to the construction paper. It is easily and inexpensively replaced.
