Backyard Volcano

Several years ago, my daughter was fascinated with volcanoes.  This is a simple backyard “volcano” you can make with everyday household ingredients.  Does it mimic a real volcano with molten reactions?  No.  But it’s a lot of fun to make something safely erupt. :)  Here’s what we did, in case you’d like to do the same:

 1.  Get a plastic bottle, and build your volcano around it.  

(You could use dirt, sand, clay, plaster, paper mache, whatever you want.

I’m a simple girl, so we dug a little hole and just piled rocks around the bottle.) 

2.  Pour about 1 cup of warm water into the bottle. 

3.  Add about a tablespoon of dish soap. 

4.  Add a few drops of red food coloring. 

5.  Add about 1/4 cup of baking soda. 

6.  Begin adding vinegar until you see it starting to foam up quickly. 

7.  Watch the fun! 




Things I would do differently next time:

1. Mix the ingredients around a bit before the vinegar gets poured in.  I didn’t think of that when burying it in rocks.

2. Use white vinegar instead of apple cider.  In past vinegar/baking soda projects I’ve done, it seems I get better reactions.  But that’s just me. 

 Have fun! :)
