Science Activities for Kids :Mini Volcanoes

Make colorful mini eruptions with recyclables

Can’t stress the gorgeousness of this science activity. Baking soda and vinegar eruptions have been done with multiple variations. Creative people out there are constantly reinventing this popular activity for a reason- it never gets old, especially to the kids. Today we share a simple twist on the same science activity.


  • Plastic Egg Carton
  • Craft Knife
  • Baking Soda
  • Vinegar
  • Squirt Bottles
  • Food color or
  • Liquid Watercolor

Cut the bottom of each slot from the egg carton using a craft knife.Snap off the lid. Flip the carton over and make “mini mountains” Fill up the lid with baking soda and have the child spoon in the baking soda inside the egg carton slots through the hole ( which is now on the top) Add lots of baking soda to make the eruptions spill over the slots.

Fill up squirt bottles with colored vinegar. I colored the vinegar using liquid water color. You can use food color if you prefer that.

    Would this work using small plastic cups? I’ve never seen plastic egg cartons – only polystyrene or cardboard.
