This cornflour slime (or gloop as it’s also known) is an easy-peasy messy play and sensory substance to whip up. It uses simple household ingredients, and Miss 2 ½ played with it for almost one hour straight, yes seriously! (That is pretty impressive considering her normally very limited attention span).
What You Will Need to Make the Cornflour Slime (Gloop)
- 2 ¼ cups cornflour (though it’s handy to have a bit extra on hand too)
- ½ cup shampoo
- 6 Tablespoons water (approximately)
- Food colouring (whatever colour you choose)
Instructions:
Mix the shampoo and a couple of drops of food colouring together.
Mix together with the cornflour.
Add the water 1 Tablespoon at a time. You may need a bit more or a bit less water to get the right consistency.
Once it’s all mixed together you have this amazing slime like dough you can play with. It should roll into a ball (if it’s too wet to roll into a ball add a little bit more cornflour). It should be nice and shiny and soften/melt in your hands (if not, slowly add a tiny bit more water).
It does get a bit messy so we played with ours outside (and I’d definitely recommend this).
Miss 2 was intrigued and not so sure to begin with but once she got her hands dirty she had a blast!
She had fun stretching it, rolling into balls, throwing it into the air and letting it splat on the table and just moulding and mixing it.

She loved making handprints in the slime then watching them slowly disappear.

It started to dry out after a while so I just mixed in a bit more water and we were good to go again.
When we were finished I scraped it into a plastic tuppaware container and kept it sealed. We played with it again daily over the next couple of days just adding a bit of water each time to get it to the right consistency.
Have fun! I’d love to hear how you get on with this activity. Did your kids love it as much as mine did? Please leave a comment below and let me know. 🙂
