Leave a tub of sudsy cornstarch goop to dry for a day, then crumble it into a fragrant, cloud-dough-like powder for scooping, molding and pretend play. It is a fun way to talk about wet and dry and how matter changes.
This goop contains soap. It is not taste-safe, so don't let kids mouth or eat it, and supervise closely with toddlers.
Keep soapy powder away from eyes. Rinse with water if it gets in, and wash hands after play.
Dry cornstarch powder can get dusty. Scoop gently and avoid blowing or tossing it near faces.
Sprinkles are food, but once they are mixed into soapy goop they are no longer safe to eat.
Small toy cars and sprinkles can be choking hazards for young toddlers. Supervise at all times.
Before the kids arrive
Make and play with the sudsy goop (see the Sudsy Goop sensory activity post).
Leave the goop in its tub to dry for a day.
Steps
Scrape the dried goop off the tub and crumble it into a soft, powdery, cloud-dough-like texture.
Squeeze handfuls of the powder together to make balls.
Set out ice cream scoops, cups and spoons in the tub.
Pack the ice cream scoops with goop to make shapes.
Turn the scoops out to make ice cream 'cookies'.
Smash the cookies with a spoon.
Pack a cup with goop and flip it over to make a 'flipped cupcake'.
Decorate the cupcakes with sprinkles.
Drive toy cars around the tub.
With older kids, talk about how the wet goop turned dry and how matter changes.
Tips
Don't toss your goop after play! I left the tub to dry for a day and found a wonderful, still-fragrant powdered cornstarch with a cloud-dough-like texture.from the author
It's just cornstarch with a bit of soap and a little moisture, so it behaves like cloud dough and you can make balls out of it.from the author
If the child is older, this is a good opportunity to show dry vs. wet and change of matter.from the author
Expect fast play: my toddler explored at lightning speed. She kept asking, 'Is this oobleck, mommy? It doesn't look like it.'from the author
Make it your own
Run it as a two-day sequence: sudsy goop on day one, then 'life after goop' dry play on day two.
The story behind it
By TurkeyMom · July 2013
I left the goop tub to dry for a day and found this wonderful, still fragrant, powdered cornstarch with a cloud dough like texture. I was able to make balls out of it.
I set out ice cream scoops, cups and spoons for a traditional sensory bin exploration. We made shapes using ice cream scoops.
This is just cornstarch with a bit of soap and little moisture, so it behaved like cloud dough. I made the ice cream cookies.
And she smashed them. My toddler adores sensory activities in general and this one was no exception. She was exploring at lightning speed!
We had a fun time making "flipped cupcakes" using the cups I set out.
And she decorated them with sprinkles. She kept asking over and again, "Is this oobleck, mommy? It doesn't look like it."
And she drove cars around in the tub. If the child is older, this is a good opportunity to show dry/wet and change of matter.
