This simple floating dry erase marker experiment is a lot of fun for kids to try! You only need a dry erase marker, a bowl, spoon and water! Kids can learn how to make their drawings float with this simple experiment!
Dry erase markers contain an oily silicone polymer. This makes the ink easy to wipe off nonporous surfaces such as a whiteboard, glass, metal or ceramic. This polymer makes the ink slippery and prevents it from sticking to the whiteboard.
This is possible because dry-erase markers contain special ingredients. They include a solvent, which is usually some kind of alcohol. This is used to dissolve the color pigments that determine the marker’s color. In addition, a resin or polymer is added.
You might know dry-erase markers can stain other surfaces such as clothes permanently. This is because fabric doesn’t have a smooth surface, so the ink can soak into its pores—staining them forever!
The colors are bright and clear, which is suitable for children's graffiti on paper, writing, and drawing in classroom lectures and office meetings as well.
Did you get your drawings to float? You should have—but only when using the dry-erase marker. When you make your drawing on the surface of a smooth plate or tray the solvent, or alcohol, that dissolves the ink ingredients will evaporate.
