Baking Soda and Vinegar Experiment

Next, blow up the balloon so you can draw a jack o lantern face on each balloon with the permanent marker or get these balloons where it is already done .

Then, fill the balloon with 3-4 tablespoons of baking soda. I used a funnel to get the baking soda into the balloon without too much spillage.

Carefully stretch the balloon over the mouth of the water bottle without letting any get in the bottle yet. When you are ready, lift the balloon so that it’s completely vertical which will dump all the baking soda inside into the vinegar.

As the chemical reaction occurs between the acid and base, carbon dioxide results. The CO2 air has no where to go so it pushes up out of the bottle into the balloon and begins filling the balloon.

The balloon will keep inflating making a super cute instant jack-o-lantern pumpkin. The pumpkin will continue to inflate until the chemical reaction of the material provided is exhausted.

So what is happening here? The baking soda and vinegar explanation is simple:

When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution. … Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.

Baking Soda and Vinegar Experiment

You can do just one growing pumpkin balloon, or several to make a whole pumpkin patch. This is such a fun, engaging way for kids to learn a little about chemical reactions with a fun WOW moment.
