This simple “magic” activity is a fun way to help your child strengthen their hands while exploring colors and cause-and-effect through play.
As children use the dropper to reveal hidden designs, they build control, coordination, and curiosity—all through a simple, engaging experience.

🧺 Materials
To make the magic pad:
