Fun Halloween Activity for Kids: Self-Inflating Ghost Balloons!

Science Magic: Self-inflating Halloween Ghost

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!

Halloween Activity for Kids: Self-inflating Halloween Ghost

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!

mesmerized kiddos :)

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. :)

    We’ve done this experiment, but not in a long time, and *certainly* not as a ghost. My kids are going to love this!

    Awesome idea! It’s been a year since we did this experiment (non-ghosty), so it’ll be fun to see J’s excitement for the experiment again and have something new, Halloween related (that’s not messy or sugary). I might steal the idea for a Halloween post. I’ll link back up to you, for sure.

    Clever idea mama! I’m featuring it this week on Tuesday Tots so if you collect featured buttons, you’re welcome to grab one of mine. Thanks so much for linking it up :D

Il palloncino va posizionato sul colla della bottiglia e alzato per far ricadere il bicarbonato nell’aceto. La chimica farà il resto.  Visto su MamaSmiles. […]
