Watch the Playdough Volcano Craft for Kids

Volcano eruptions are fascinating for kids, bubbling, foaming, and flowing like real lava. This playdough volcano craft combines creativity and simple science to create a safe and exciting experiment at home or in the classroom.

Using everyday ingredients like baking soda and vinegar, kids can build their own volcano and watch it erupt in seconds. It’s messy, fun, and a perfect introduction to basic chemical reactions.

What You’ll Need

Materials

  • Playdough (homemade or store-bought)
    : You can use our homemade playdough recipe or reuse old playdough
  • Baking soda
  • Dishwashing liquid (optional – for more bubbles)
  • Vinegar
  • Red food coloring (optional)
  • Spoon
  • Small cup
  • Tray or large plate

How to Make a Playdough Volcano (Step-by-Step)

1. Build the volcano

Use playdough to shape a volcano on a tray.
Make a hole in the middle for the eruption chamber.

4. Prepare the lava

In a small cup:

  • Pour vinegar
  • Add a few drops of red food coloring

Mix gently to create red “lava”.

The Science Behind It (Kid-Friendly)

When baking soda (base) meets vinegar (acid), they react and create carbon dioxide gas.

That gas forms bubbles, pushing the liquid upward, just like a volcanic eruption!

This is a great way to introduce:

  • Chemical reactions
  • Cause and effect
  • Observation skills

Safety Notes

  • Adult supervision recommended
  • Do not taste the ingredients
  • Protect clothes and surfaces (it can get messy!)
  • Wash hands after play

Learning Benefits

This activity helps children develop:

  • Fine motor skills (shaping playdough)
  • Early science understanding
  • Curiosity and problem-solving
  • Sensory exploration
  • Creativity

Why We Love This Activity

  • Uses simple household items
  • Quick setup
  • Very engaging for kids
  • Combines craft + science
  • Works for preschool to early primary age

Perfect for rainy days, homeschool science, classroom experiments, or weekend fun.

Final Thoughts

This playdough volcano craft is a fantastic way to turn science into play. Kids get to build, experiment, and learn, all while having fun watching their volcano erupt again and again.

If you want to extend the activity, try:

  • Making different colored lava
  • Measuring how high the bubbles rise
  • Drawing a volcano diagram afterward

And don’t forget,the homemade playdough makes this activity even more special
