Fizzing Mud Experiment

It's super muddy out there with all the storms we've been having, but rather than get blown over, why not bring the fun of mud indoors with our Fizzing Mud experiment!

You will need:

  • Baking powder or Bicarb

  • Corn flour

  • Dark food colouring

  • Water

  • Bowl

  • Vinegar



How-to:

  1. Combine roughly equal amounts of baking powder and corn flour into a bowl.

  2. After mixing well, add roughly 2 teaspoons of dark food colouring (preferably brown, or mix a few colours together to get brown)

  3. Begin to add a splash of water and mix, slowly adding more water until the consistency is thick and mud-like.

  4. Slowly add 4 teaspoons of vinegar and watch it fizz!


Extended learning:


Preschool - Early Years

  • Why not tell the story of 'Going on a bear hunt' by Michael Rosen & Helen Oxley ..."Uh oh, thick oozy mud, we can't go over it, we can't go through it, we're going to have to go through it"

  • Add animals to the mix before adding the vinegar - watch them sink and little hands having to retrieve them!

5yrs+

  • This isn't just fun for the little ones, ask the older kids to measure out the ingredients, and then mix them together to get the desired consistency.

  • Perhaps ask them to think of a story, or song that includes fizzing/bubbling mud (to the rhyme of a well known song or nursery rhyme).

  • Also, another idea is to ask them to create a 3D swamp scene first and then add the bubbling mud and of course mud monsters! Download our 3D mud monster below.

A Few Tips:

  • We used food colouring to colour our fizzy mud, but it can tinge the kids hands for a few hours after play. If you are worried about stained skin you can use black washable watercolours in place of food colouring.

  • This activity is messy. We recommend laying an old blanket or drop cloth down under the play surface. Play clothes or smocks are also a good idea.

  • Fizzy mud is only good for one play time and should not be stored for future use.
