Fine motor fun with an eyedropper and bath mat
This eyedropper and bath mat activity is an absolute blast and the perfect way to build those tiny hand muscles!
All you need is an upturned bath mat, an eyedropper, and some colorful water.
Turning the bath mat upside down so the suction cups face up creates endless possibilities for filling, squirting, and experimenting.

This eyedropper and bath mat activity is simple and SO FUN
I have been doing this activity with preschoolers forever now and I am still always taken aback at how much KIDS. LOVE. THIS.
It’s the simplest thing. You might even think it looks…boring. But oh, my goodness, this activity is always *electric.*
Kids will fill the suction cups over and over and over and over and the joy is off the charts the entire time.
Plus, we have some fun ideas on how to add even more fun, challenge, and interest!

How to set up an eye dropper and bath mat activity
- Fill small containers with water and add a few drops of food coloring to each.
- Turn the bath mat upside down so that the suction cups face up.
- Show kids how to use the eyedropper to draw water and then carefully squeeze it into each suction cup.
- Encourage kids to explore color mixing by adding drops of different colors to the same suction cup.
- Watch them laugh, focus, and squirt away!
Color mixing is one of the best parts of the bath mat and eyedropper fine motor activity
Kids are mesmerized by color mixing and this activity is the perfect opportunity to practice this skill.
I usually model by saying something along the lines of, “Want to see how I make lime?” First, add a little bit of green into a cup and then a lot of yellow.”
Kids are hooked.
Some easy colors to make:
- Red + yellow = orange
- Pink + blue = purple
- Purple + blue = indigo
- Red + green = brown
- Orange + yellow = marigold
6 more ideas with your eyedropper and bath mat
- Color Mixing Challenge: Encourage kids to combine two colors in each suction cup and observe the result. This helps them learn about primary and secondary colors.
- Pattern Play: Ask kids to create patterns (like alternating colors or making stripes) across the bath mat. This activity strengthens both creativity and fine motor skills.
- Counting Practice: Have children count each drop they add to a suction cup, or count how many cups they fill with each color.
- Race to Fill: Set a timer and see how many suction cups they can fill in a minute. This adds excitement and builds hand-eye coordination.
- Rainbow Rows: Challenge them to make a rainbow by filling rows with red, orange, yellow, green, blue, and purple water.
- Letter Formation: Use the eyedropper to “write” letters or numbers in the cups, making it a great preschool literacy activity.
Making it perfect for older and younger kids
This eyedropper and bath mat activity can be easily adapted for toddlers, preschoolers, and even early elementary kids!
For younger kids, offer some assistance with squeezing the eyedropper until they get the hang of it. They’ll still get to practice those fine motor skills while exploring basic color recognition.
For older kids, challenge them to create patterns, experiment with mixing colors, or even use the eyedropper to “write” letters in the suction cups! Adding a bit of structure keeps them engaged while making it feel like a creative challenge.
This flexibility makes it a preschool fine motor activity that grows with your kids’ skills.
