Cody and I were looking through one of our science books, and decided to do one of the experiments. It's a super easy one but it gave us an opportunity to discuss chemical reactions and...ya know...anything that's fizzy is fun! :)
What you need:
baking soda
balloon
funnel
vinegar
bottle
Pour vinegar in the bottle, about half an inch deep.
Using the funnel, put two teaspoons of baking soda into the balloon.
Or use a piece of paper rolled up if your funnel happens to be in your son's moon sand in his closet.
Stretch the balloon over the neck of the bottle
and quickly tip the balloon so that all of the baking soda falls into the bottle at once.
You might want to hold the balloon in place, although ours seemed to hang on pretty well.
The baking soda reacts with the vinegar to create carbon dioxide.
The gas spreads out to fill the space so the balloon inflates.
Your balloon may look like this...
or like the crystal skull from the newest Indiana Jones movie.
Then make faces and give your brother's balloon rabbit ears.
