Pumpkin Volcano 

It is only right that one of the Halloween experiments your family does includes a pumpkin. This one is super simple, requiring items in your pantry to make it happen. For less mess inside, it is best to try this one outdoors, but can also be done in your home with proper preparation. The eruption will be slow and steady, but please be cautious. A great thing about the pumpkin volcano is it can be done over and over again.  

Items needed: 

  • Small hollowed out pumpkin, with top cut off 
  • White vinegar 
  • Liquid dish soap 
  • Food coloring 
  • Baking soda
  • Tray or pan (if experimenting inside) 

Instructions 

  1. Fill the inside of the pumpkin halfway with vinegar 
  1. Add a tablespoon of dish soap 
  1. Add 2-3 drops of food coloring 
  1. Mix the liquids with a spoon, until bubbles start forming 
  1. Add 2 ½ tablespoons of baking soda 
  1. Watch your volcano erupt 

Rising Ghosts & Jack-O’-Lanterns 

This Halloween experiment will for sure have your family saying, “BOO!” This activity will be scary-cool as you start to see ghosts and jack-o’-lanterns float seemingly by magic. You will use ghosts and jack-o’-lantern balloons that inflate without losing your breath. If you don’t have traditional Halloween balloons use white and orange and draw faces on them using a permanent marker. There are two different ways to make your ghosts rise, fast or slow, both are easy.

  1. Place balloon opening over the neck of the water bottle and lift it up making the baking soda fall into the vinegar

Witches Brew

  • Pineapple juice

Magic potion 

Staying with the witch and wizard theme, making a potion will make your children really feel like they are creating magic. Similar to the pumpkin volcano this Halloween experiment will have a foamy explosion. Make it feel like you’re not at home and pretend like you are casting a spell while the potion explodes and comes to life. Please supervise children because this is not edible.

  1. Add a tablespoon of dish soap into the bottle and swirl around 
  1. In a separate cup, mix ¼ cup of warm water and yeast until fully dissolved 
  1. Pour the water-yeast mixture into the bottle 
  1. The potion will start to slowly explode and spill over into the large container 
  1. Add a few drops of a different food color to the foam 
  1. Use the Popsicle sticks or skewers to make designs with the food coloring and pretend the potion is whatever they like
