The Volcano Experiment

Experiments are one of my boy’s favorite things to do. They love to see the reactions that different substances can make together and how things work. The volcano experiment below is one of the easiest ones to do and only takes a few minutes of prep time. It is also relatively mess free if done right. I did put it in the 6+ category though, because little ones may be tempted to touch or taste and that likely would not be good. We even made a video this time so you could get an idea of the reaction that takes place.


  • Large casserole dish or cookie sheet
  • Clear glass bowl
  • Vinegar
  • Food coloring
  • Baking soda
  • Spoons

Step 1:

Place a few drops of food coloring on each spoon.

Step 2:

Fill each spoon up with baking soda. The more you use the bigger the volcanic reaction will be.

Step 3:

Place the clear glass bowl inside the casserole dish or on the cookie sheet and fill with a few cups of vinegar. This will keep the mess contained should the liquid spill over the bowl.

Step 4:


Place the spoons in the vinegar mixture and stir them around for a few seconds to release the color. Watch the volcanic eruption occur!

  1. baking soda and vinegar is a classic.  🙂
    we did a variation where it made a “bomb.” 
    make sure you have a water tight zip top bag (quart size, test with water and then use duct tape on any leaks)
    put vinegar in the bag
    put baking soda wrapped in a paper towel.  (at this point you should probably be outside)
    drop the paper towel package into the baggie.
    close the bag.
    wait for it… … POP!
    the kids loved it.

    1. Thanks Susan! That was actually on our list of 70 summer crafts and experiments to try that I posted last week LOL. Can’t wait for the boys to try it.

  2. Have you ever heard of making “Witch’s Brew?”  It only calls for two ingredients: dry ice and hot water. 
    If you put the dry ice in a big bowl, and pour just about 1/2 cup of water on it, the result is fascinating….  
    Thought you might have either heard of it or want to try it.  

    Love your site! 

    God Bless,
