Fun Project: Colorful Mini Volcanos

Photobucket Pictures, Images and Photos

This is a fun science project for kids from preschool on up.  While it may not hold the same science lesson for a child passed the third grade, it retains its value in entrainment.  So go ahead and let all the kids give this one a try.  Make sure you have your table covered since the reaction between the baking soda and vinegar can get out of hand.  Go slowly, unless you want to see a huge explosion.  My kids decided to make a huge reaction right at the end and it really was fun.

Colorful Mini Volcanos


  • Baking soda
  • Vinegar
  • Liquid food coloring
  • Eye droppers
  • Disposable pan for easy clean up
  • Small cups to mix food coloring and vinegar


  1. Sprinkle baking soda in your disposable pan.  Cover the entire bottom of the pan.
  2. Mix your food coloring and some vinegar in a few small containers.
  3. Using an eye dropper, you will add vinegar mixed with food coloring, to your disposable pan of baking soda.
  4. As the colorful vinegar hits the baking soda it will react and the “volcano” will be in color!

My kids loved doing this project.  They continued to add more vinegar and baking soda to watch it bubble up.  We had it get a bit out of control which was exactly what they intended.  Just make sure you keep your table covered because you may get some of it spilling on your table.  Another good  tip is to keep your food coloring out or reach of small children.  Be careful with small hands during this activity.  However, it is suitable for young children since it is completely non-toxic.  I had as much fun as the kids playing with this one.  Experiment with different colors and different amounts of vinegar and baking soda. Ask your kids what they think will happen if more of one element or the other is added.  Don’t forget to have fun!
