What could be more fun than mucking around in a big pile of mud?  Making it FIZZ!  Rosie and Jewel had lots of fun with this activity, and they got to explore elements of science while fully engaging the senses.

Read on to see how we made mud using just two ingredients!

For all the best kids activities follow us on Pinterest and Facebook.

Today, we combined a few ingredients to make the most amazing play mud for kids, and the best part is that this recipe is super "clean".  If you are apprehensive about your children playing in real mud give this activity a try! 

How to Make FIZZY Mud for Kids

Baking soda
Corn starch
Food coloring


Begin by combining roughly equal amounts of baking soda and corn starch in a large bin or container. 

Add 2-3 spoons of black food coloring.
Then, slowly begin to add water and mix, slowly adding more water and mixing until the desired consistency is reached.  You want the mixture to be mud-like but not too saturated.

Add toys and diggers, and the fun can begin!

FIZZY Mud is great fun just like this and makes a fantastic sensory material perfect for all sorts of play.  The corn starch in this recipe makes the mud sticky and gooey, and it also turns from a solid to a liquid as kids play!  You really must give it a try!

Extend the Fun
Give kids squirt bottles of vinegar to make the mud FIZZ!

Rosie and Jewel thought this was so cool and had a blast making eruptions in the mud.

We colored our vinegar with food coloring, and that added a really fun element our play.  The red vinegar was especially colorful against the black mud.

Rosie and Jewel had so much fun!  I refilled their squirt bottles several times.  Then, once we were all out of vinegar they continued to play in the mucky mud, creating all sorts of fun with their dinosaurs.

A Few Tips:  

We used food coloring to color our fizzy mud, but it did tinge the kids hands for a few hours after play.  If you are worried about stained skin you can use black washable watercolors in place of food coloring.
This activity is messy.  I recommend laying an old blanket or drop cloth down under the play surface or playing outside/in the bathtub. 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.
