Just imagine the fun you could have with an Erupting pumpkin after you carve your pumkins on halloween

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 some 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!
