Here is the classic chemical reaction activity many kids love! We put the small container in the center of the Lego volcano for adding baking soda and vinegar. We looked up volcano images on the internet and observed which Lego color we should use. Then we built the volcano around the small container. I wanted to use legos instead of other materials because I thought it might be easy to clean or wash.


What We Used

We did this experiment under adult supervision.

  • Small or tiny container to place in the center of the Lego volcano
  • Legos (we used black, brown, orange, yellow, red and grey colors)
  • Lego baseboard
  • Vinegar
  • Baking soda
  • Adult supervision

We setup the small container on the lego baseboard, then we built the shape of volcano around it.

We brought our Lego volcano back yard and started the experiment. We added the baking soda to the small container that is inside of the volcano. Then finally, my son added the vinegar. Ready! Set! Go!

Bubbly eruption! My son was SO excited, and he added vinegar into the container many times and used up the whole vinegar in the bottle!! He made me laugh because he had hysterical laughing every time he added vinegar and saw the fizzy bubbles. It was so much fun and worth our time cleaning up!
