So are permanent markers really permanent? It’s all about the solubility of the ink, or in simpler terms, how easy it is for something to dissolve. A good example of something that’s soluble is sugar. When you mix sugar with a liquid and stir it it appears to magically disappear, but it’s not really gone because you can taste it. That’s because it is soluble, or easily dissolves in liquid.
Try this fun activity, suitable for early elementary aged kids, and let them learn about the wonders of science through permanent markers!
