Read on to see how we made bubbling BOOS & popping pumpkins.
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
- Baking soda
- Corn starch
- Vinegar
- Zip-seal bags
- Food coloring
- Black marker
- Toilet paper
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.
- 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.
- 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!
My kids love a good baking soda and vinegar reaction and had WAY TOO MUCH fun with this simple twist of science.
They marveled at each explosion, eagerly setting off bomb after bomb.
I hope your kids have fun with this activity! Make sure you have lots of baking soda and vinegar on hand, as they will surely want to make baggies explode again & again!
