Bubble Pumpkin Volcano

We’re adding a new twist on a classic fall craft for kids. Make a pumpkin volcano that erupts with bubbles! This is a pretty simple experiment that involves ingredient reaction to produce a lava flow of bubbles. If you’ve ever made a pumpkin volcano you know what supplies you need, but be sure to check below for that one special ingredient that makes this volcano science project different. Also, this is a pretty messy activity so you may want to take it outside before putting the ingredients in the pumpkin. Parents, make sure you cut a lid in the pumpkin and take the seeds and slime out yourselves, or supervise older kids for safety.

Once your volcano has erupted kids may be excited to play with the bubbles. Because of the addition of vinegar the bubble lava will have an odor so be sure to keep little hands away. If you do plan to let your kids play with the bubbles please check for a skin reaction to the ingredients involved to be sure your child isn’t sensitive to them.

Supplies

  • A pre-gutted pumpkin
  • Baking soda
  • Vinegar
  • Dish soap
