Science Camp- Part II

Given the amount of cleanup that was required after our first science experiment, I thought it would be best to take things down a notch. There would be no microwaving or bubble making.

Everything we needed for the experiment is here:

Let me rephrase that, everything you'll need is in the foreground of this picture. You won't need the fruit bowl, baby wipes or whatever that colorful thing is on the right.

So, to be clear, that's:

Empty Water Bottle
Vinegar
Baking Soda
Funnel (optional)
Measuring Spoon
Balloons
Kids (Not pictured and optional)

First you put a teaspoon of baking soda into a balloon. The funnel was really helpful with that part. Then, put three tablespoons of vinegar into the water bottle-- again, I recommend the funnel.

Stretch the opening of the balloon over the opening of the water bottle.

The kids were skeptical.

Or maybe just goofy.

Lift the balloon so that the baking soda pours out and into the bottle.

And then watch the magic happen!

Sorry, but the magic is not that the balloon changes colors! But it does expand. We did this several times with several balloons. It was a real crowd pleaser.

I liked this experiment a lot because it didn't require any special ingredients- we had everything on hand, it was easy enough for a three-year-old to actively participate and it was very quick. Within seconds the balloons started to rise.
