Baking soda, vinegar, dish soap, food coloring, muffin tin, medicine dropper, bowl
Add a spoonful of baking soda, a drop of food coloring, and a squirt of dish soap into each muffin cup. Put vinegar in a bowl, then let your toddler use the dropper to add it and watch the “eruption.” Tip: Ask them to mix vinegar with different colors and notice new hues. You can also teach patterns using colors!
