I know you may be thinking this may be some kind of cooking experiment gone wrong, but hey this IS a recipe and it was fun to make so I figured I would give you all the ingredients to make an Exploding Volcano! So grab the kids, your crazy friends or just yourself and make an exploding volcano, hey it gives you something to do and a reason to get messy!

Exploding Volcano
6 cups flour
2 cups salt
4 Tbsp oil
2 cups water
1 plastic bottle (2 liter, we used 2 (.5 liter) water bottles)
baking sheet
warm water
red food coloring
6 drops liquid dish detergent
2 Tbsp baking soda


  1. Create a salt dough by mixing the flour, salt, oil and 2 cups water in a large bowl. Mix with your hands until the dough is smooth and firm. Add a little bit more water to the mixture if needed.
  2. Stand the clean plastic bottle(s) in the middle of the baking sheet. Mold the salt dough around the bottle(s), making sure that you don’t cover up the bottle mouth (the hole at the top) or drop any dough into the bottle(s). Take your time and build the volcano of your dreams! We used two different bottles so we could do different colors in each bottle.
  3. Add the food coloring to the bottle(s). Fill the bottle(s) most of the way with warm water mixing with the red food coloring.
  4. Add liquid dish detergent into the bottle. Add baking soda to the water/detergent mixture in the bottle.
  5. Slowly pour vinegar into the bottle and jump back!

Notice the red “lava” that flows out of your volcano. This happens because of the baking soda and vinegar mixture. By mixing the two together you produce a chemical reaction in which carbon dioxide gas is created – the same gas that bubbles in a real volcano! The gas bubbles build up in the bottle, forcing the liquid “lava” mixture out of the bottle and down the sides of your volcano. I got this experiment from 2 Cool Baby.

  1. now that looks like just too much fun!!! I bet my girls would have fun with that too!

  2. It was fun, it is all about the memories:)

  3. I WANT TO DO THIS!!!! We never did this stuff as kids. We didn’t even get to make a volcano. Just the tornados in soda bottles.

  4. Oh, you should do it then Rick:) Tornadoes in soda bottles are cool, too…lol

  5. I loved this “experiment” in elementary school, but lost the recipe somewhere along the way of growing up. Thanks so much for sharing :)

  6. Wow this brings me back to the good ole days, but what fun! I should have done this while waiting for my car yesterday!! :)

  7. What a fun mess…I remember these types of adventures when mine were little. What a blast:)

  8. this looks a recipe for a good ole fashioned mess! You know, I bet many people would avoid this just because of the mess, but that is what makes it so much fun. I remember it taking me 20 minutes to get the batter off my hands! then my wife showed me how to do it and it came right off. You gotta try it and have the camera/video camera nearby to capture the memories!
    Thanks CCRECIPE!

  9. Frank, it definitely is ALL about the memories:)
