How To Make Frozen Oobleck

Hot Summer days are the perfect excuse to be outside with messy play. Frozen oobleck is such a perfect activity for this and it literally doubles the fun and play time of normal oobleck. “Oobleck” is just a fancy term for good old cornflour and water and with the help of some silicon moulds this is one super fun activities and absolutely safe for younger babies and toddlers to experiment with.

You’ll Need:

  • cornstarch
  • water
  • liquid watercolors or food coloring (optional)
  • ice-cube trays, silicone molds, or a container to place in the freezer

How to Make the Frozen Oobleck:

  1. Add about 1 cup of cornflour to a bowl.
  2. Slowly add about 1/2 cup of water. I found with this you want to almost double the amount of cornflour to water, because your freezing it, to make sure it melts into a proper gooey oobleck. Less water is better!
  3. Add food coloring or liquid watercolors. Obviously for younger kids you would want to use food colouring as its non-toxic.
  4. Pour the oobleck into molds. We used our favourite Mickey shaped moulds, because someone turns 90 on the 18th of November!
  5. Place the molds in the freezer for at least a few hours.

Take it outside! This activity was perfect and the boys banged about trying to break up the frozen moulds for ages before getting stuck into the gooey mixture afterwards. it goes without saying its messy, but that’s why we were in our swimming suits ready to rinse off in the pool afterward. Interest was held for much longer. Once melted, It has properties of both a solid and a liquid depending on the amount of pressure applied. When you press down, the cornstarch and water mixture acts like a solid, but when constant slow pressure is not applied, the mixture acts like a liquid.

The perfect activity for summer holidays coming up!
