Dry Erase Marker Floating Fish On water | Diy science Experiment| Fun STEM Activity| Float Drawings
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.
In contrast, a permanent marker has an acrylic polymer that makes the ink stick to the surface, instead of being slippery.
How Does it Work?
You can get your drawings to float with a dry erase marker. When you make your drawing on the spoon (or a plate) the solvent that dissolves the ink ingredients will evaporate. Then, the color pigment and polymer is left on the spoon. However, since it has an oily silicone polymer this prevents it from sticking to the spoon.When you dip the spoon into the water, the water can slip underneath the drawing since the polymer prevents it from sticking to the spoon. Finally, since the ink is lighter than the water, it floats!
Supplies Needed
Blue Dry Erase Marker – we tested the Ikea Brand and the EXPO brand. Make sure the marker says it is NOT washable. If it is a washable marker it will not work.
A round bowl or dish
Metal spoon
Water – we used regular tap water. It was cold water. We did not test with hot water.
Some tips (as this may take a few tries to get it to work!):
Dont use washable markers use Dry earse markers
Draw thicker lines
Make sure all of the lines are connected to each other
You want to press down so that a lot of ink comes out (if it’s too light it might not be thick enough to hold together)
