In this tutorial, we learn how to make a graffiti mop from a repurposed cleaner bottle. First, you will take stamp cleaner in a small bottle that you can pick up from any craft store and a bottle of Pilot ink (1 oz). Next, empty the stamp cleaner from the bottle and then pour the ink into that bottle using a dropper. After this, place the top back onto the bottle and shake it for several seconds. When done, take the cap off and you will be able to write on a wall now using this bottle's soft top. The writing will bleed a little bit, so be careful where the ink goes.
