Making Cornflour Gloop

Just one cup of warm water...

And two cups of cornflour later...

Makes hours of messy gloopy, tactile fun....

But here's the science bit...

Apparently this mixture is a non Newtonian substance.
The surface wrinkles and forms ripples when blown on, you can drag a paint brush through it and even slide it right out of the bowl.

However the substance is responsive to pressure and when touched or hit with an object it immediately hardens to a solid.

It has the weirdest texture and is really fun to play with.

Here's a step by step guide on you tube with lots of great ideas for playing with your own gloop.


  1. Oh we do love this stuff;-) Milly - who is always up for experimenting in this way - likes to add liquid paint and shaving foam to hers! xx

  2. Oh, what fun!
    Such great photos! : )

  3. Gotta try this, looks like great fun! Thanks for the idea.

  4. It is interesting too. DH would just go ape at the mess and goop on the fingers...He doesn't like finger painting either! what fun!!!! Cathy

  5. I'm glad you let your kids make a mess. :) By the way, I'm sorry I'm just getting back to you about this - THANK YOU for the blog award. I wrote about it on my post today. I also passed on another award to you. I appreciate your respect for God, nature, photography, and the written word.


I treasure each and every one of your comments.
Your kind words never fail to bring a smile to my face:)
At the moment I am going through a busy season of life with 5 girls under my wing! I may not always be able to respond immediately but please know that every word left here is read and appreciated deeply.
