Turn a science experiment classic into the ultimate Halloween science for kids experience!
Recognize this post? I’m sharing it again today along with other fun hands-on Halloween activities for kids from friends!
Ghost Balloons! Halloween Science for Kids
Ghost balloons make easy Halloween science for kids! – all you need is a water bottle, balloon, Sharpie pen, vinegar, and baking soda! This is a fantastic Halloween science experiment for groups – check out the group photo from enjoying this experiment with my son’s second grade class below! Last year a friend and I ran this experiment for at least 100 kids as part of the kids’ noon science program at school.
Draw a ghost face on the balloon, and fill it with about 1 Tablespoon of baking soda. Fill the water bottle with about half a cup of vinegar. Attach the balloon to the top of the water bottle, lift the balloon so that the baking soda falls into the water bottle, and watch the magic happen!
This activity is a great one for large groups of kids! My son’s second grade class made these fun ghost balloons.
How Do Halloween Ghost Balloons Work?
The two household chemicals, baking soda and vinegar, create carbon dioxide when mixed.
These process photos were taken using a pink balloon for three-year-old Lily. The pink-ness makes it a particularly friendly ghost, I think. :)
Emma used our small camera to capture the entire thing on video:
Which we’ve uploaded to Youtube! Enjoy!
