{Little Mad Scientists} Volcano!

Written by Mommy Cameron | Homeschooling

Ever since my boys saw the new chipmunk movie, they have wanted to learn about volcanos.  So, after doing some searching I found a volcano experiment that I wanted to try with the boys.  The reason I chose this version of making a volcano was that the bubbles in this version are filled with the same gas that make bubbles in real lava.

8 oz glass or plastic bottle
2 Tbsp yeast
2 Tbsp honey
6 C. flour
2 C. salt
4 Tbsp cooking oil
2 C. water
1 C. warm water
Large bowl
Baking Pan


1.  In a large bowl mix flour, salt, cooking oil and water to make a playdough like mixture.  Add water, if necessary, to make the dough stick together.

2. Put honey into the small bottle.  Then fill it half way up with warm water.  Shake the bottle until the honey dissolves.

3.  On the baking pan, using the dough mixture begin to roughly shape a volcano.  Make sure to leave a hole in the center for the bottle.

4.  Add yeast to the bottle and shake it again.

5.  Finish filling the bottle with warm water.

6.  Place the bottle in the center of your volcano.  Then finish molding the dough into a volcano around the bottle.  Make sure that you do not let any of the dough fall into the bottle.

7.  Then wait for the lava to flow.

I was a little disappointed because the eruption wasn’t as exciting as I hoped it would have been.  In hindsight I should have just used baking soda and vinegar, I think the boys would have enjoyed that reaction more.  Also, I would have used some red food coloring in the mixture so that the lava would have been easier to see.  (I guess I should have listened to my husband.)

However, the boys really enjoyed watching the volcano erupt.  At one point all three boys were sitting around our outdoor craft table.  It was great family time.

Have you ever made a volcano?

  1. The way you made the volcano is a way I’ve never seen before. The mixture for the lava is different than see before too. Even though it wasn’t as exciting as the vinegar and baking soda I still want to try it with my kids. Everyone uses the vinegar kind but it’s cool to try a different way too. Very fun. I’m trying to think what else we could do with the reaction of the mixture you used. I’m sure that would bake a great reaction experiment activity.

    I am just hopping over to thank you for linking up this week to my Enchanted Thursdays Blog Hop! Wow, I have seen a lot of different ways to make volcano’s but never like this. This looks very fun! The kids facial expressions are too cute also!

    Interesting-we’ve done the vinegar and bicarbonate version many times but this is a bit different. Isn’t the gas carbon dioxide in both cases though?
