Oobleck is always so much fun to play with, frozen oobleck is even better! Kids can mix up their own oobleck using just cornflour and water and watch the 'slime' as it changes from a solid to a liquid. This simple science activity for toddlers and preschoolers will keep young children busy for ages as they explore and experiment. Today we introduced little fish to our oobleck sensory play.

You will need:
- 2 cups of cornflour (cornstarch)
- 1 cup of water
- Food colouring
- Tray to pour the oobleck into
- Ice cube trays
How to make frozen oobleck
To make the oobleck simply mix the water and cornflour together and pour it into a tray. If you want coloured oobleck add a little food colouring. We added blue colouring to make it look like water for the fish to swim in.
I love getting the kids involved in the process of making the oobleck. Its always fun to explore the difference between the cornflour by itself and once water has been added. (scroll down to see a video of the activity in action)
Once you have had time to explore and play with the oobleck a little put the tray into the freezer for an hour or so. Mix up a little extra oobleck and pour it into ice cube trays. You may want to use a few different colours so that you can explore what the colours do as they melt and mix together. We love using different shaped ice cube trays, for this activity we used the fish ice cube tray from ikea.
Frozen Oobleck Sensory Play
When the oobleck is first taken out of the freezer its rock solid, but it melts quickly. Daisy (aged 2) loved playing with the little frozen fish. She said they were cold and watched carefully as they began to melt and the colours ran into one another.
After a while the oobleck in the tray had melted enough to be able to pick it up. Daisy managed to get her hands under it and pulled up big pieces of oobleck that were still frozen.
Once it had melted a little more she picked up handfuls of gloop and watched it trickle out of her hands.
We love adding small toys into our play. Today we added a polar bear.
Exploring frozen oobleck is a really fun sensory play activity for toddlers and preschoolers, one we come back to again and again. Yes it does make a mess, but it is so much fun!
