Rosie loves the old baking soda and vinegar trick, and we are always trying to come up with new and fun twists for this experiment! It truly never gets old! All you need for this activity is a carved pumpkin, some baking soda, and vinegar. Food coloring is optional but highly recommended as it adds to the fun Science!
We filled our pumpkins with a bit baking soda and a few drops of food coloring. We didn't measure, but I estimate we used about 4 tablespoons of baking soda per pumpkin. Then we added the vinegar and the eruptions began!
Our hope was for the whole pumpkin face to erupt, but the pumpkins were so large and the mouths so big that the eruptions only came out of the mouth. However, Rosie didn't care one bit! She thought the erupting pumpkins were so cool!
To some this may look a little gross, but it is a Halloween activity after all ;) We plan to experiment with smaller pumpkins to see if we can get the eruptions to come out of the entire pumpkin face. I am certain that with a little tinkering, we can make this fun Science experiment for kids even cooler!
