Pumpkin Volcano experiment for kids - Supplies:


  • 1 cup white vinegar
  • ¼ cup baking soda
  • Food colouring, if desired
  • 1 small pumpkin
  • Melon baller
  • Sharp knife

Pumpkin Volcano experiment for kids - Instructions:



STEP 1: First things, first!



Gather your supplies and prepare the surface you'll be working on. I recommend doing this before inviting the kids to be part of the experiment as we'll be using a knife to cut the pumpkin, and it is best to do it without little ones running around! If older children are doing this experiment they may enjoy preparing for the experiment themselves.

STEP 2: Prepare the pumpkin.



Take a sharp knife and start by removing the stem from your pumpkin. Then, make a large hole inside your pumpkin by using a melon baller to remove all the seeds.

STEP 3: The magic ingredient.



Once you finished the previous step, take the baking soda and add it to the inside of your pumpkin.

STEP 4: Mix your magical concoction.



For this step, you should decide if you want to use food colouring. You can do this volcano experiment without, but I recommend adding a contrasting colour to make this experiment much more fun!

Add the food colouring to the baking soda (or alternatively to the vinegar).  Next, pour the vinegar over the baking soda inside the pumpkin.

STEP 5: Watch the bursting result of this experiment.



Now it's time to watch the extraordinary eruption burst! Making your pumpkin volcano erupt is so much fun!!!!!
