Halloween Science Activity

This Halloween Science Activity is one of our favorite baking soda and vinegar experiments. I love putting together fun activities that are themed around holidays and one of my 7-years-olds favorite holidays is Halloween so, of course, I had to put together a baking soda and vinegar activity. 

You can find all the supplies for this Halloween Science Activity from Target or Walmart. I’ve even linked some of our favorite activity supplies below. Check them out if you do a lot at home science or DIY projects.

This one is pretty simple and loads of fun. First, grab an activity tray or a Halloween serving  tray and a mini plastic pumpkin. You can usually find these cheap at Walmart this time of year. If you plan on more science activities in the future, invest in the large box of baking soda. Although, a small one will be sufficient for just this experiment. You’ll also need some cups, white distilled vinegar, liquid food coloring, and small plastic spiders. That’s it! Check out the step-by-step instructions below and have fun!

Supplies Needed:

• Baking Soda
• White Distilled Vinegar
• Liquid Food Coloring
• Activity Tray
• Mini Plastic  Pumpkin
• Mini Plastic Spiders
• Small Jars or Cups
• Spoon

Directions:

1. Fill the mini pumpkin with about 3 spoonfuls of baking soda. You can use more if desired. 
2. Pour all of the mini plastic spiders on top of the baking soda.
3. Pour some vinegar into jars or cups with a few drops of liquid food coloring. I found some cute Halloween-themed jars in the Dollar Spot at Target.
4. Make your hypothesis about what will happen when you add the vinegar to the baking soda filled pumpkin. Sample questions below.
5. Add as much vinegar as you’d like to the pumpkin and see what happens!
6. Tip: Add about 6-8 tablespoons of baking soda and a lot of vinegar and the spiders will explode out of the pumpkin!
7. After the filing stops, it’s also fun to feel the baking soda mixture after vinegar has been absorbed into it. Just don’t let those tiny fingers go in the mouth!

Sample Questions:

1. What will happen when the baking soda and vinegar mix together?
2. Do you think the spiders will overflow out of the pumpkin?
3. Will the colored vinegar be visible once it’s added to the baking soda- will the baking soda change colors?
4. How long will the fuzzies last?
5. What will the baking soda feel like after it mixes with the vinegar?
