How To Create A Watermelon Sensory Bin

What You’ll Need
Here’s everything you’ll need to make a batch of kinetic sand. If you’re worried about younger kids putting it in their mouths, you might want to try making our Taste-Safe Kinetic Sand Recipe which uses food-grade ingredients.
- 2 cups Play Sand (we used red play sand but any color works!)
- 1 1/2 cups Cornstarch
- 1/2 cup Vegetable Oil
Extras for the watermelon sensory bin:
- Dried Black Beans (for “seeds”)
- Mini Plastic Watermelon Slices
- Wooden loose parts, Rocks, Gems, or other summer-themed trinkets
- Silicone Cupcake Liners or Small Bowls
- Scoops and Funnel, Tongs and Tweezers, Spoons, or cookie cutters
- Sensory Bin (or any container big enough for your child to play in).

Kinetic Sand Instructions
1. Mix Dry Indredients
Add 2.5 cups of fine play sand and 1.5 cups of cornstarch into a mixing bowl. Stir well to evenly distribute everything.
3. Add Oil
Slowly mix in the 1/2 cup oil.
3. Mix It All Together
Use your hands to knead the mixture until it’s fully combined and has a soft, moldable texture. If it’s too dry, add a tiny bit more oil. If it’s too wet, sprinkle in a little more cornstarch.
4. Optional Extras
If you’re feeling fancy, now’s the time to add a few drops of essential oils for a lovely scent or a sprinkle of glitter for some sparkle. Just make sure it’s safe for kids and won’t irritate sensitive skin.

How to Set Up Your Watermelon Sensory Bin
1. Fill the Bin
Start by adding your homemade kinetic sand to your sensory bin or large container. Spread it out evenly across the base to create a bright, soft, moldable base. This is your “watermelon flesh” ready for play!

2. Add Watermelon Items
Sprinkle in the black beans to act as watermelon “seeds.” Then, add your mini watermelon slices, pink and green wooden loose parts, sparkly gems, and any summery trinkets you have on hand.

3. Add Scoops and Tongs
To make the bin even more interactive, toss in some scoops, tongs, and bowls to give your child even more ways to interact with the bin. These tools promote fine motor development as kids scoop, dig, and explore.

4. Let Them Play
Once it’s all set up, invite your little one to dive in and explore! They can pretend to slice watermelon, bury and dig out seeds, or just enjoy the sensory texture of squishing and molding the kinetic sand.


Creative Play Ideas For Your Watermelon Sensory Bin
You can do so many things with this watermelon sensory bin! Don’t be surprised if your little one spends a solid 20 minutes just running their fingers through the sand. It’s that satisfying! Want to take it up a notch? Here are a few ideas:
1. Watermelon Bakery
Turn your kitchen into a pretend watermelon dessert shop! With silicone muffin liners, cookie cutters, and small bowls, kids can shape the kinetic sand into “cupcakes” or “cookies.”
2. Sensory Treasure Hunt
Bury small watermelon-themed trinkets in the dough and let your kids dig them out using scoops or tweezers. It’s a fun surprise element that keeps them engaged!
3. Free Play
Sometimes the best moments come from unstructured exploration. Let their imagination flow! Ask questions like, “What’s growing in your watermelon garden?” or “Can you plant more seeds?” to inspire deeper imaginative play.

Tips for Making the Most of Your Kinetic Sand
Safety When Playing with Sensory Bins
Sensory bins are amazing, but it’s always good to keep a few safety tips in mind:
- Supervise younger kids. If you have toddlers or babies playing with the bin, always keep an eye on them to make sure they’re not putting any small objects in their mouths. Choking hazards are a real concern, so be mindful of the size of the objects you include.
- Watch out for sharp or fragile items. Avoid anything that could potentially break or shatter in the bin. Stick to soft or flexible items like plastic figures, pom-poms, and silicone or plastic scoops.
- Keep it clean. Sensory bins can get messy! Lay down a sheet or tablecloth underneath to catch any runaway sand or small pieces. This makes cleanup a breeze.
