Are you getting ready to carve pumpkins with your kids like you do year after year? Bring a new twist to pumpkin carving this time by adding STEM! This is such an easy and instantly rewarding activity. Your kids will be delighted by the exploding foam escaping out of their pumpkin’s face, as well as the fun to touch texture of baking soda, vinegar and soap.
To get started:
- Baking soda
- Liquid dish soap
- Cookie sheet or large flat container (optional to contain the pumpkin and fizz from the chemical reaction)
1. Ahead of time, cut the top off the pumpkin and clean the inside of the pumpkin out like you would do when preparing to carve a pumpkin.
2. Carve any type of pumpkin face out of one side of the pumpkin.
3. Gather all your supplies and place them nearby.
4. Drop a heaping amount of baking soda into the pumpkin. We didn’t really measure the ingredients, but added about a cup of baking soda to our medium sized pumpkin.
5. Add dish soap to the baking soda. Again we did not measure. Have the kids squeeze a good amount into the pumpkin.
6. When ready, Pour vinegar into the pumpkin until the mixture begins to react, and place the pumpkin top back on.
You can wash out the pumpkin and redo it as many times as you want. For an extra spooky look, add some food coloring!
