Halloween Science Experiment: Ghost Balloons

This week I am sharing fun and easy Halloween science experiments and activities!  Today, we are making Ghost Balloons! They're a great science project that teaches kids about chemical reactions.

If you love blowing things up with vinegar and baking soda, make sure you see our quick and easy balloon science activity and the more Halloween-y growing glove experiment too!  We took the basic idea from these activities and used a ghostly balloon to celebrate the Halloween season.  Of course, if you're not particularly fond of Halloween, you could use the same concepts without the ghost!

Simple Supplies:

* white balloon
* black sharpie
* water bottle
* vinegar
* baking soda
* optional: funnel

Easy How To:

1.  Draw eyes on the white balloon.  Make them nice and dark...they will definitely lighten as the balloon expands!

2.  Add about 2 tablespoons baking soda to the balloon.  I like to use a funnel.  Be careful not to smudge the eyes!

3.  Add about 1 cup of vinegar to the water bottle.

4.  Secure the balloon to the water bottle, making sure the baking soda does not fall in accidentally.  If you are using a 12" balloon (which I do recommend!), slide as much of the "neck" down on the water bottle as possible (without breaking the balloon, of course!).  This will help the balloon stand up better.

5.  Quickly shake the baking soda into the balloon and watch your ghost grow!  We especially liked how the eyes lightened as the balloon stretched.

6.  Let your kiddos touch, play, and experiment with the ghost!

What's Happening:

This science experiment teaches kids about chemical reactions.  The vinegar and baking soda react with each other to form carbon dioxide, a gas that bubbles up, out of the bottle, and into the balloon!
