Eraser features a soft pile that removes markings quickly and cleanly from dry-erase surfaces. Age it Up: Try using different liquids and drawing surfaces and compare the results.Age it Down: Practice writing letters and do the experiment with those.The marker drawing is less dense than the water, and floats on it, giving it a life-like quality. The lack of adhesive is also what allows the water to make the drawing “come to life” and float, rather than sticking to the dish. They also have very few adhesive qualities, which is why they can be easily erased. Leave the marker until you see the ink start to run in the liquid. Keep your marker vertical so the tip points down and dunk the tip in the alcohol. Fill a small bowl with 90 rubbing alcohol so you have enough to submerge the tip of your marker. Buoyancy: the ability of an object to floatĭry erase markers are insoluble, meaning they can’t be dissolved in a liquid like water. Soak the tip of the marker in rubbing alcohol to rewet it. ![]() We have been Canadas premiere industrial supplier for over.
