This experiment explores chemical reactions.  For more fizzing science check out how we made a glow-in-the-dark volcano!

Bubbling Boo & Pumpkin Bombs

Materials
Method
  • Start by drawing jack-o-lantern and ghost faces onto zip-seal bags.  
  • We used a permanent marker and sandwich-size bags.  Larger bags will also work; you will just need more of the active ingredients.
    Once the marker on the bags is dry you can either fill them all in advance with the vinegar or fill them outside as you go.  
    • You want to fill each bag roughly 1/3 of the way with vinegar.  
    • Add 2-3 teaspoons of corn starch to each bag.

    • You will also want to add orange food coloring to the pumpkin bags.
    • Then, tightly seal the bags and mix the ingredients until combined.

    Making Baking Soda Bombs

    For each bag you will need to make a baking soda bomb.  To do this place baking soda in the middle of a square of toilet paper, and then fold the paper into a ball.

    Setting off Exploding Sandwich Baggies
    • You will want to let off one "Boo" or pumpkin at a time.  
    • Seal the bag almost all the way, leaving just enough room to place a baking soda bomb in.
    • Do not let the bomb go until you have sealed the bag all the way.

    • Double check to make sure the zipper is fully sealed.
    • Then, drop the baking soda bomb, give the bag a quick shake, and set it down.  
    • The bag will fill with pressure until it POPS & explodes, sending colorful bubbles flying!
