EXPERIMENT 8 Sparkling water sparkles
You will be producing this gas from vinegar and baking soda — a
household ingredient that is used for baking. The experiment will
also show you that the gas dissolves in water.
You will need:
balloon, drinking straw, as well as: 2 empty, thin-
sided plastic water bottles with caps, vinegar, baking soda (in the
supermarket baking section), teaspoon
It’s the gas known as carbon dioxide that gives sparkling
water its sparkle.
1
Fill the first plastic bottle about a
quarter of the way with vinegar, and the
second bottle about a third of the way
with cold water.
2
Using a spoon, carefully put about
2 to 3 teaspoons of baking soda into
the balloon. The measurement does
not need to be exact.
3
Pull the balloon opening tight over the neck of
the first bottle, but be sure to let the body of the
balloon hang down to the side so that no baking
soda falls into the bottle yet.
