Rosie carefully shapes another little ghost.
She smooths the soft, icy foam with her hands, gives it a funny face, and proudly admires her newest creation.
Then someone hands her a spray bottle.
Everything changes.
One squeeze sends the ghost fizzing into a bubbly mess, and suddenly she's no longer making ghosts.
She's chasing them.
Before long she's creating new ghosts just so she can blast them away again, laughing as every squirt transforms the soft foam into a wonderfully fizzy Halloween surprise.
That's what makes Ghost Foam so unforgettable. Children don't simply build something and admire it. They create, imagine, experiment, and then joyfully transform their own creations into something completely new.
Whether you're looking for a Halloween sensory activity, a playful baking soda science experiment, or a hands-on play recipe filled with squishy textures and fizzy surprises, Ghost Foam invites children to build, explore, and discover one ghost at a time.

How to Make Ghost Foam
Step 1. Make the Ghost Foam
Pour the baking soda into a large sensory bin, then gradually add the shaving cream a little at a time. Stir gently as you mix until the ingredients come together into a soft, fluffy foam that's cool to the touch and easy to mold.
One of the most enjoyable parts is discovering how the texture changes as you mix. Children often pause along the way to squeeze, crumble, and explore each new stage before adding a little more shaving cream.
Step 2. Build your ghosts
Cut simple ghost shapes from black craft foam and invite children to press them into the soft Ghost Foam. They can build one friendly ghost or create an entire haunted Halloween scene filled with silly faces and spooky surprises.
Soon the sensory bin becomes its own little ghost world.
Step 3. Become a Ghost Buster
Hand children a squeeze bottle filled with vinegar.
Then stand back.
Every squirt sends the little ghosts fizzing into a bubbly, disappearing mess. Children quickly discover they can build another ghost just so they can blast it away all over again.
One ghost almost always turns into another.
Step 4. Discover Ghost Mud
Eventually the fizzing slows, but the fun doesn't.
As the vinegar mixes with the Ghost Foam, the texture changes once again into a wonderfully squishy Ghost Mud that's just as fun to explore as the foam itself.
Children squeeze it, scoop it, and create brand-new ghostly creations before adding another spray of vinegar to bring the fizzing back again.
One play recipe.
Three completely different sensory experiences.
Why Kids Love Ghost Foam
Children never quite know what comes next.
First, they're squeezing soft, icy foam through their fingers.
Then they're carefully building friendly little ghosts.
Moments later they're laughing as every spray of vinegar makes those same ghosts bubble, fizz, and disappear before their eyes.
That's what makes Ghost Foam so memorable. Every stage feels different, giving children new textures to explore, new discoveries to make, and another reason to keep playing just a little longer.
Frequently Asked Questions
Does Ghost Foam have to fizz?
No. The Ghost Foam is wonderfully fun to play with all on its own. The vinegar simply adds another playful science experience when children are ready.
Why is the Ghost Foam cold?
Baking soda naturally feels cool when it's mixed with shaving cream, giving the foam an icy texture that makes it feel especially fun for Halloween play.
Can we use something besides black craft foam?
Absolutely. Paper ghost cutouts, plastic Halloween figures, cookie cutters, or even children's fingers work beautifully for creating ghostly designs.
What happens after all the vinegar is gone?
The Ghost Foam transforms into a wonderfully squishy Ghost Mud that children can continue molding, scooping, and exploring. If you'd like more fizzing fun, simply add another little spray of vinegar.
What age is this activity best for?
Preschoolers and elementary-aged children especially enjoy the changing textures and fizzy reactions. As always, supervise young children during sensory play.
