Vinegar and baking soda play is always a hit with little ones :) The first experiment I filled plastic egg cartons with drops of food coloring or drops of dish soap and then covered them with baking soda. Gave the kids a small cup with vinegar and a dropper and let them experiment.
The next experiment we put baking soda in the balloons and vinegar in the bottles. Place the balloon over the rim of the bottle and shake the baking soda down to the vinegar. The reaction creates a gas and the balloon blows up!
The last experiment was dish soap and baking soda in the small cup and pour vinegar over it to watch the reaction :)
I LOVE being a homeschooler!!!
