More Ocean Sensory Fun!

It’s been a fun few days here at Twodaloo headquarters- Daddy took the week off from work so we have been enjoying a little “staycation” here in DFW.  Today we took the twins to the Grapevine Sea Life Aquarium for an encore visit, which reminded me that I have several more ocean-themed sensory activities to share with you!  These are activities we have done in addition to our Ocean-themed unit and our fabulous Sensory Lagoon, so be sure to check those out if you are looking for more fun ocean ideas for toddlers and preschoolers.

Activity #1: Oobleck Ocean

One afternoon, after discovering an ancient box of cornstarch in our pantry, I created an impromptu ocean by mixing the cornstarch with water and some teal food coloring to create blue “oobleck.” If you’ve never mixed cornstarch with water before, you are really missing out on a very strange sensory experience!  I made ours a bit on the watery side to begin with, but as it dried out in the Texas heat I discovered that the substance seems to defy the laws of physics…as long as you keep it moving, it behaves as a solid, but as soon as you put it down, it morphs back into a liquid.

We simply added our sea creatures, a few bowls, pails, and shovels, and we were good to go!


We made a colossal mess all over the patio, but it was easily cleaned up with the water hose.  And it didn’t cost me a thing!

 Activity #2: Cold Sea Foam

This was another spur-of-the-moment activity I put together to occupy the twins during the “witching hour,” which at our house is around 4:30, or after nap/snack but before Daddy gets home from work.  It’s too late (and hot) to go anywhere, but too early for dinner…what’s a busy toddler to do but whine or get into mischief?  On this particular day I grabbed a plastic container, stole a few squirts of my husband’s shaving cream, and threw in some “ocean ice” that I had set aside for just such an occasion. I found some cheap sea creature ice molds at Ikea last Spring and snatched them up knowing they had about a jillion uses.  I dug them out when we started our ocean unit and filled them with water and blue food coloring.  It was nice to have this fun ice on hand, but regular ice could easily be substituted in its place!

Syd wasn’t too sure at first…look at her wrinkly nose!

Will joined in and both kiddos enjoyed picking out all the sea creatures and placing them carefully into their little buckets.

And then dumping them right back out again.

 They also enjoyed painting every inch of our patio furniture with the shaving cream using their shovels as “brushes.” When Daddy got home, they painted his jeans, too.  Hey, whatever keeps them happy, right? It’s all in the name of learning 😉

Activity #3: Jellyfish in a Bottle

This has to be my favorite activity from this post- I got the idea from BhoomPlay, and after a bit of trial and error, the finished product turned out awesome! Check out her post for details, she even has a short video of her son playing with his jellyfish, which illustrates just how cool this sensory bottle is in motion!

This is not an activity that can be easily created with younger kids, because it takes a bit of finagling to get it to work right.  I made mine yesterday during nap time so the kids could discover it when they woke up.  I used Smart Water bottles as the containers (I removed the labels with some Goo Gone) and a thin plastic bag from the produce aisle of the grocery store for the jellyfish.

The only other change I made to the original tutorial was instead of using thread to tie off the bubble that creates the “hood” of the jellyfish, I used one of my daughter’s tiny elastic hair bands.  I was having trouble getting the thread tight enough to hold in the air and water needed to make the jellyfish float and sink when the container was flipped, but the stretchy band solved my problem.

Sydney was up first from her nap, and she found our new “pet” right away.  It really seems to be alive inside the bottle because the little air bubble makes it “swim” up from the bottom every time you flip it over.

She brought it right over to Daddy to tell him all about it.

Then she had to compare our new jellyfish to the picture of the jellyfish in our ocean picture book.

And then she couldn’t resist giving all the jellyfish a big fat smooch 😉

It’s safe to say she liked it!  Now that I have figured out the logistics of creating these little guys, next time I plan to embellish the jellyfish a bit with some tiny ribbon or metallic string mixed into the tentacles.  Fun, fun, fun!

  1. These are wonderful and look so much fun. I love the Jelly fish in a bottle – will have to try that next time we do ocean themed stuff.

  2. Just hopped over from Tuesday Tots – absolutely love these ideas, so creative. The ice sea creatures are fab, perfect for a hot day.

  3. The jelly fish is amazing! I can’t wait to try it. Thanks for sharing at Mom’s Library!

  4. Hi may I know what’s the ocean picture book u have in the picture above?

  5. Whether its quartz, granite or solid surface black is the color for
    2014. They often invest deeply in areas they feel have strong cultural potential, and their
    acquisition of The Lord Baltimore Hotel indicates the beginning of
    what is sure to be a long-term commitment to the cultural
    life of Baltimore City. This type of kitchen remodeling is done when
    your cabinets are generally sturdy and not in need of more
    than cosmetic work.

  6. Howdy! I could have sworn I’ve been to this site before but after checking through some of
    the post I realized it’s new to me. Anyhow, I’m definitely happy I found it and I’ll be book-marking and checking back often!
