Children don't just watch where the ghost lands.
They watch where the cloud goes.
For a few quiet seconds, everyone follows the swirling white powder as it drifts through the air before slowly disappearing. Then another little ghost is ready for its turn.
That's what makes these ghost bombs so much fun. Every gentle toss creates another mysterious puff of ghostly "smoke," inviting children to laugh, explore, and wonder what the next ghost will do.
Whether you're planning a Halloween party, looking for an outdoor science activity, or simply hoping to surprise your little ghosts with something unexpected, these ghost bombs turn a handful of simple materials into a playful Halloween tradition children will ask to do again and again.

Supplies
You'll only need a few simple materials to make ghost bombs that disappear in a swirling puff of ghostly "smoke."
You'll need:
- Hollowed eggshells
- Cornstarch or baby powder
- Black permanent marker
- White tissue paper
- Glue stick
You'll also need:
- A small spoon or funnel for filling the eggs
- An outdoor space for tossing the ghost bombs
- An adult to help prepare the eggshells
How to Make Ghost Bombs
Step 1. Prepare the ghosts
With the help of an adult, carefully crack the top of each eggshell and empty the contents. Rinse the shells with warm water, then allow them to dry completely before decorating.
Saving breakfast eggshells makes this activity feel even more magical.
Step 2. Decorate your ghost bombs
Use a black permanent marker to draw silly, spooky, or surprised ghost faces on each eggshell.
One by one, each little ghost begins to come to life.
Step 3. Fill the ghosts
Carefully spoon cornstarch or baby powder into each eggshell until it's mostly full. Try filling some ghosts a little more than others and see how the swirling white cloud changes with each toss.
Cover the opening with a small square of tissue paper and seal it in place with a glue stick.
Now your little ghosts are ready.
Step 4. Toss and watch
Head outside and gently toss one ghost onto the ground.
For just a moment...
The ghost disappears.
Then, a soft white cloud swirls into the air.
Children don't watch where the ghost landed.
They watch where the cloud goes.
Then another ghost is ready for its turn.
Why Kids Love Ghost Bombs
The fun doesn't end when the ghost hits the ground.
That's when everyone starts watching.
Children follow the soft white cloud as it swirls, drifts, and slowly disappears into the air. Some toss their next ghost right away. Others pause to see how long the ghostly "smoke" will dance before it's gone.
Every ghost is a little different.
One ghost creates a tiny puff.
Another sends a much bigger cloud swirling through the air.
Before long, children are comparing their ghostly creations, experimenting with different amounts of powder, and cheering every time a new cloud appears.
That's what makes ghost bombs so memorable. Children aren't simply tossing eggshells. They're discovering how one gentle throw can transform into a floating cloud that seems to disappear like magic.
Extend the Play
One ghostly cloud always leads to another.
Try filling some ghost bombs with different amounts of powder and compare the clouds they create. Which ghost leaves the biggest puff? Which one disappears the fastest? Children naturally begin making predictions, testing their ideas, and watching closely to see what changes.
You can also decorate each ghost with its own funny face or expression before tossing them one at a time. Soon children are giving them names, choosing favorites, and deciding whose turn comes next.
Sometimes the most interesting part isn't the throw.
It's watching the little ghost slowly disappear into the wind.
Frequently Asked Questions
Are ghost bombs safe for children?
Yes, with adult supervision. The ghost bombs are made with simple household materials, but they should always be tossed away from faces and never at another person. Encourage children to stand back and enjoy the ghostly cloud from a short distance rather than breathing in the powder.
Can we use baby powder instead of cornstarch?
Absolutely. Both create a fun ghostly cloud when the eggshell breaks. Cornstarch is a great pantry option, while baby powder creates a similarly dramatic effect.
How far should children throw the ghost bombs?
A gentle toss is all it takes. The goal isn't to throw them as far as possible. It's to watch each little ghost disappear into its own swirling cloud.
Can we make the ghost bombs ahead of time?
Yes. Once the eggshells are filled and sealed with tissue paper, they're ready whenever your Halloween celebration begins. Store them somewhere dry until it's time to play.
What age is this activity best for?
Older preschoolers and elementary-aged children especially enjoy decorating, tossing, and watching the ghostly clouds appear. Younger children can help decorate the ghosts while an adult prepares the eggshells.
