I have one classroom ingredient that can turn a completely ordinary preschool day into the kind of day children announce to their parents before they have even taken off their backpacks.
It is inexpensive. It is easy to find. It can fit almost any theme, and it requires very little preparation.
It also has a habit of taking my perfectly reasonable activity plans and turning them into something much messier than I intended.
I am not telling you what it is just yet.
It started as a fire-safety activity
During fire-safety week, I taped pictures of fires around the classroom. My plan was for the children to walk around with pretend fire extinguishers and put out each fire.
In my head, it was going to be cute, simple, and memorable.
Then the activity started, and I discovered one tiny problem: the children did not have enough finger strength to press the cans.
I tried helping them one at a time. That sounded like an easy solution, but it meant everyone else had to wait. Most of the children quickly lost interest and moved on to something else.
At that point, the activity I had planned was pretty much over.
But two cousins stayed.
The secret ingredient was shaving cream
The pretend fire extinguishers were cans of shaving cream.
Since the two children were still interested, I sprayed some out for them and let them spread it with their hands. That was supposed to be the new version of the activity.
It did not stay that way for long.
Soon they were on the floor with shaving cream on their arms and pants. They kept looking at me like they were waiting for me to say, “Stop!”
Instead, I laughed.
That was apparently all the permission they needed. They spread it farther, covered themselves from head to toe, and started “swimming” in it.
My fire-safety activity was long gone. I was standing there watching two children swim through shaving cream and thinking, Oh my goodness. What have I gotten myself into?
I sent their parents videos through Brightwheel. The parents loved them. One of the boys called it the best day ever.
Honestly, I felt the same way—even knowing I had to clean all of it up.
Why shaving cream works so well in preschool
Shaving cream is one of my favorite preschool materials because it does not have to be one specific thing.
I can provide the starting idea, but the children decide where it goes. They can smear it, scoop it, draw through it, mix colors into it, cover toys with it, or simply enjoy the feeling of it moving through their fingers.
It is also forgiving. There is no correct finished product and no example the children are expected to copy. A child can touch it with one finger, use a tool, or put both arms into it. Everyone can enter the experience differently.
Shaving-cream activities for different preschool themes
Once you start looking at shaving cream as a flexible classroom material instead of one activity, it can become almost anything:
- Snow: Add animals, scoops, cups, or loose parts for a winter invitation.
- Clouds: Use it during a weather theme and let children explore storm clouds, rain, or cloud shapes.
- Ocean foam: Pair it with sea animals, shells, or blue water for an ocean setup.
- Car-wash soap: Add toy cars, brushes, and a tub of water for rinsing.
- Frosting: Offer pretend cupcakes, play dishes, or bakery tools during dramatic play.
- Construction cement: Let children spread it between foam blocks or recycled boxes with toy tools.
- A drawing surface: Children can make lines, shapes, pictures, letters, or completely invented marks with their fingers.
- A color-mixing experiment: Add small drops of washable color and let the children discover what happens.
Or it can just be shaving cream.
It does not always need a themed purpose. Sometimes putting a pile on the table and letting the children figure out what to do with it is enough.
If you want more ways to turn ordinary classroom materials into open-ended play, my Play Beyond Purpose bundle is built around that same idea.
The part that matters more than the theme
The children in my fire-safety activity did not remember the carefully placed fire pictures. They remembered being allowed to follow the play somewhere unexpected.
They kept checking my face because they expected an adult to stop them. When I laughed instead, the entire experience changed.
That does not mean every classroom has to allow children to cover themselves from head to toe. We all have different spaces, schedules, rules, and amounts of cleanup we can realistically handle.
But it is worth asking whether we are stopping something because it is unsafe—or simply because it is messier than the picture we had in our heads.
That is the question at the heart of Just Let Them: Why Preschoolers Need the Freedom to Get Messy.
A few things that make the mess easier
- Protect the floor or nearby cabinets with a shower curtain, plastic tablecloth, or another washable covering.
- Let the adult dispense the shaving cream, especially when using an aerosol can.
- Keep it away from faces and remind children that it is for play, not for tasting.
- Have towels and water ready before the activity begins.
- Remember that shaving cream can make hard floors slippery, so clean dropped foam as you go.
- Follow your program’s policies and the product directions, and offer tools for children who do not want to touch it.
The real secret
Yes, shaving cream is my secret ingredient for an unforgettable preschool day.
But the shaving cream was only part of what made that day special.
The children remembered that they were allowed to be completely inside their play. I did not pull them back to my original plan just because their idea was bigger, sillier, and much messier than mine.
The cleanup took time. Their clothes were covered. My activity looked nothing like I imagined.
I would still do it again.
The classroom moments that stay with us are rarely the ones that followed the plan perfectly. Stories like this are part of the preschool-teacher book I’m writing about what children have taught me when I slowed down, watched, and let the day become theirs.
