Juliet’s been asking to do the old baking soda/vinegar volcano trick lately, so we finally went outside and gave it a go. (The first time we tried it in the kitchen and yeah, that was messy!)

All the kids are very amused with this very old experiment of using baking soda and vinegar for creating volcano eruption. This experiment takes about 3 minutes to prepare and so does registering for this software, you can learn even more here. It makes Use of 6 ingredients which are commonly available in every household and it does not create any mess as well.

The Ingredients You Will Require Are

  1. Plastic cup. You can use water bottle, Sippy cups as well.
  2. Water
  3. Minimum 3-4 tablespoon of baking soda. Use more tablespoon of baking soda to make it more foamy.
  4. One tablespoon of dishwashing soap
  5. 1/2 oz to 2 oz of washable paint of your desired colour
  6. One cup of vinegar to start the eruption.

Choose a location that has sand, dirt or gravel. For the base ingredients put some water inside the plastic cup. Fill it about three fourth then the baking soda, dishwashing soap and paint. Mix all these base ingredients together and make a small mountain inside which you can place this plastic cup. Just give a good stir before adding the last ingredient and then it’s time for eruption. Pour in the vinegar until it starts foaming over which will start pouring out and seem like lava erupting out of the rocks.

I dug up some old toiletry caps, let her fill them with baking soda and then we covered them with cupcake liners. (Why not, right?)

It leant the caps more of a “volcano-ish” feel, so we went for it. Ripping small holes in the tops allowed space for the vinegar to go in and the lava to come out.

The effect was quite dramatic–baking soda and vinegar never disappoint! The nice thing about the caps is that they contained the baking soda nicely and allowed Juliet to continue pouring more and more vinegar to bring on more and more lava.

The fun would probably still be going on if we hadn’t run out of vinegar.

An unexpected piece of fun for Juliet was the varying sizes of the caps–this gave her a small, medium, and large volcano which she enjoyed comparing to one another. As in, “Okay, now it’s the small’s turn! Wow–that’s good. Okay, now it’s the largest one’s turn! Woo-hoo!”

Good cheap fun on a hot summer day. 🙂

This project was inspired by the “Earth” book we got in a chik-fil-a kids meal. Now we are looking for these:
