The water can then slip underneath, and because the ink is not as dense as the water the drawing will float. But in fact, there is an oily silicone polymer in the dry-erase marker that prevents it from sticking to your plate. When you draw with the dry-erase markers, it looks like the color is sticking to the plate. It’s all because of the type of ink in the marker, which doesn’t dissolve in water unlike the washable markers in our coffee filter flower STEAM project or marker chromatography experiment! This dry erase marker and water actually demonstrates the physical properties of dry erase ink and water! Explore chemistry with this magical little demonstration! Larger designs fall apart when they begin to float. ago Try storing them in a ziplock baggie forrestlurrkerr 3 yr. It should write better immediately unless it has dried out completely. This was not tested on glass or plastic (but that would be a fun variation to try to make the experience more scientific!) You can either store them point down for a few days, or, for more fun, tape the back end of a marker to a string really well, and whirl it around in circles for 30 seconds.
