– Baby Oil

Clear sensory bottles

– Small fish toys and seashells

Ocean Sensory Bottle with Baby Oil

Safety Note About Baby Oil: 

Baby oil should be kept out of children’s reach. Ensure the lid is properly sealed and cannot be opened by children by hot gluing the lid on. Always supervise during play.

 

Learn About Density

This sensory bottle can also be a fun science lesson on density. Oil and water do not mix. Oil is less dense than water and floats on top of the water. Food coloring is water-based so it mixes with the water.

After mixing and turning the bottle upside down you will see bubbles forming in the water. Once you set the bottle down the oil will begin to rise to the surface and settle on top of the water again.

For another oil and water experiment, see our fireworks in a jar experiment.

How to Make an Ocean Sensory Bottle

1. Mix blue food coloring with some water until it’s a light blue color (make sure it’s not too dark or you won’t be able to see the shells or toys).

2. Add the water into the sensory bottle until it’s halfway full.

Add Colored Water to Bottle

3. Add sea shells and any ocean animal toys into the bottle. Don’t add too many items or they will be harder to move around in the bottle.

Add Fish Toys to Bottle

4. Fill the remaining bottle with the baby oil. Do not leave too much air at the top or the air will be trapped in the bottle.

5. Hot glue the top on the inside and then secure the top on.

6. Now you can swirl the bottle back and forth to make the waves and bubbles.

Kids will love making the fish swim around in this ocean in a bottle!

Storage: store upright in a place out of reach of children.

  1. I just found your site and am soo excited for all of the fun stuff!! This looks like something we will be trying soon!! Wondering what your thoughts are on adding a couple teaspoons of beach sand into the sensory bottle? Maybe I should rinse it in clean water first…?🤔

      You can add sand in! It will sort of cloud the water up when you wave the bottle back and forth. But the sand will settle on the bottom if you let it sit.
