The kids will have a blast exploring this bottle, AND they’ll also have a plethora of learning opportunities! Here are just a few of the preschool concepts packed into this simple activity:
- Counting
- Measuring
- Volume

- Sink versus float
- Proprioceptive input
- Vestibular development
When it comes to learning opportunities, the list above is just the tip of the iceberg. I often find that the kids will get the most out of some activities if we just let them take the lead!

And as always with sensory bottles, you can change the materials based on what you have on-hand or your theme. I’ve found that mermaid charms are in very high demand!
Regardless of what you put in your mermaid sensory jar, the kids will have so much fun while learning!
Before we move on to the directions, I did want to mention that it was difficult finding any kind of diverse mermaid beads. Not for a lack of trying though! Hopefully soon there will be more options. Mermaid tail beads are a great place to start while waiting, though.
How to Make a Mermaid Sensory Bottle
Now, it’s time to get started!
Sensory bottles are super easy to create. So you can definitely involve the students if you want to! They’ll get to learn about some cool science and math concepts along the way.
First, add the entire 5-ounce bottle of glue to the empty sensory bottle. You can add up to ten ounces of glue, depending on how quickly you want the charms to move through the liquid. If you want the contents to move slower, add more glue.
Next, add the fishbowl beads! We chose purple and blue beads because they matched our mermaid charms really well. But you can include the colors of your choice.

Then drop in the mermaid charms. I love how it looks like the mermaids are just resting on the ocean floor at this point.

After that, you’ll want to fill the remainder of the bottle with water and then tightly close the lid. This is where you might want to use the tape or hot glue to secure the lid. This will keep the jar from leaking and provide an additional layer of safety.

Finally, shake the bottle to mix the contents and you’re all set!
