What you'll need:
1 teaspoon of warm water
A few drops of food coloring
1 cup vinegar
1-2 tablespoons of baking soda
Cups (we used some small plastic cups, the explosion happens quickly so it's good to have a lot set up to keep their attention)
Take the water and mix in the food coloring
Add the baking soda
Pour in the vinegar and wait for the explosion!
This was SUCH a fun activity! We let Evie pour the vinegar and she had a BLAST! Milo loved watching it too! We went through and entire bottle of vinegar in one sitting, it was so great!
