We’ve had an extra messy afternoon today mixing coloured gloop with dinosaurs, people and Mega Bloks and placing it all in our tuff tray. Gloop is probably one of my favourite sensory play mediums after playdough. It never fail.s to amaze me how it can change from being solid to a liquid and then back to a solid again. This post contains affiliate links.

Georgia’s current favourite book is Dinosaurs in the Supermarket which is about a little boy in a supermarket that has dinosaurs making a lot of mess throwing food everywhere. The adults don’t believe him though as the dinosaurs keep hiding. I’ve wanted to do some activities based around this book for awhile and knew whatever I chose needed to be extra messy like the book and the coloured gloop turned out to be perfect option.


Usually I just set up gloop sensory play as just gloop in a bowl or container as its wonderful enough just to explore as it is but adding extra things to it definitely increased the amount of time gloop is usually played with.

You will need:

  • Cornflour (or corn startch)
  • Water
  • Food colouring (optional)
  • Tuff tray or large shallow container
  • Any toys added to it are also optional. We added some toy dinosaurs and HappyLand characters

I never bother measuring out the gloop we just keep going until we’re happy with the consistency but I would say its about 2 parts cornflour to 1 part water approximately.


  • Mix the cornflour, water and food colouring altogether in a bowl. I usually let the Little Tots join in with this stage and sometimes find it easier for them to use their hands to mix it rather than a spoon.


Gloop (or Ooblek) is not for the faint hearted but if you cover up surfaces and preferably do it outside I promise you your little ones (and you) will love it. If you haven’t ever tried this amazing stuff go and do it now. If you’re still not sure test out a small bit in a bowl and I guarantee you won’t be able to stop playing with it.


I set this up after lunch and Georgia is still playing with it nearly an hour and half later and I’m amazed how much of the book she has memorised after she said it out aloud whilst playing. She has been reenacting some parts of the book and had great fun pretending to be the dinosaurs throwing the gloop (food) around and then hiding the dinosaurs so the people can’t see them.

At the end of the book the little boy gives the dinosaurs a mop and bucket so they can clean up the supermarket dso tomorrows play will involve lots of water and bubbles added to this……and so saves me a job of having to clean it up!
