Then pour some water on your plate to cover the drawing.
Do you see a difference from how the dry-erase marker looked on the surface? Next use a permanent marker to make a drawing on the second plate.What happens to the ink after a while? Does your drawing begin to float and come to life? If nothing happens, shake the plate a little bit. Then pour just enough water onto your plate to cover the drawing. Does your finger wipe off the drawing, or can you still see it afterward? Let it dry for a couple of seconds and then use a dry finger to wipe across your drawing.Does it look like the ink is sticking to the surface of your plate? Choose one color of your dry-erase markers and make a drawing on your first plate such as a stick figure, a heart or word.Fill your cup with room-temperature water and set it next to your trays or plates.Find a work area that can tolerate water spills.Two shallow trays or plates with smooth surfaces that you have permission to draw on with markers.Find out how this difference affects how your drawings float in in this activity! Only the type of polymer differentiates a permanent marker from an erasable marker. This is because fabric doesn’t have a smooth surface, so the ink can soak into its pores-staining them forever! In real permanent markers the resin used is an acrylic polymer that functions as a “binding agent” and makes the ink stick to the surface. You might know dry-erase markers can stain other surfaces such as clothes permanently. This is why the ink can easily be wiped off from a very smooth nonporous surface such as a whiteboard or glass. In a dry-erase marker the resin is an oily silicone polymer, which acts as a “release agent.” This makes the ink of the marker very slippery and prevents it from sticking to the whiteboard’s surface. In addition, a resin or polymer is added, which is the key to making the ink erasable. This is used to dissolve the color pigments that determine the marker’s color. They include a solvent, which is usually some kind of alcohol. This is possible because dry-erase markers contain special ingredients. The writing from these markers can easily be erased from the whiteboard without leaving any marks. To draw on this surface, your teacher probably uses a whiteboard pen or dry-erase marker. You might have a whiteboard in your school classroom. It turns out they are also perfect for doing science! These markers are usually used to write on whiteboards or glass surfaces and can easily be erased. What makes this possible is the interesting chemistry of dry-erase markers.
