Water Painting Pen! Was It Magical?!

Use this floating whiteboard pen to paint on the ceramic spoon or other object with a smooth face. When encountering water, the drawn pattern will float by itself, as if there is life, which is very interesting! Children can experience the joy of crafting! It's conducive to the children's sensory development.
But unfortunately, what we did in this video has failed. Maybe there are better brands of this magical pen that we could try next time.
