My kids LOVED this fun science-based Halloween activity that we came up with! It’s very simple, too – all you need is a water bottle, balloon, Sharpie pen, vinegar, and baking soda!
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!
The two household chemicals create carbon dioxide when mixed, and this inflates the balloon! This balloon experiment is one that we’ve done before, and it never ceases to amaze my kids!
Here’s a second one, done with 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!
