Discover the magic of floating Easter art with a simple experiment that turns your favorite holiday drawings into a floating masterpiece!
MATERIALS
Whiteboard markers (bright colors preferred)
A white plate or
Water
STEPS
Start by drawing your Easter designs (such as eggs, bunnies, or flowers) directly onto a white plate using whiteboard markers.
Once you’re done drawing, carefully add a small amount of water onto the plate’s surface.
Slowly tilt the plate to make the water spread evenly across the surface.
Watch in awe as your drawings begin to float!
For added fun, use a small sponge or pipette to move the drawings around on the water’s surface.
The drawings float because the special ink in whiteboard markers repels water, allowing the ink to stay on the surface of the water. This experiment teaches us about surface tension and how different materials interact with water, making it a fun way to learn science through art!
CONCLUSION
Why does this happen?
The ink in whiteboard markers is considered special because it contains a combination of pigments, solvents, and resins that make it water-resistant.
The primary reason why the drawings float in the water is due to the hydrophobic nature of the ink. This means the ink doesn't mix with water, allowing it to stay on the surface.
Here’s how it works:
Pigments provide color.
Solvents allow the ink to flow and dry quickly.
Resins help the ink stick to surfaces, but they also make it resistant to water.
Because of these properties, when you draw on a surface like a white plate and then add water, the ink remains on top of the water rather than dissolving, creating the floating effect. The surface tension of the water also plays a role, keeping the ink from sinking.
