The Rising Hand (or balloon blown-up)
Materials
Three teaspoons
of white vinegar
One medical
latex glove (or balloon)
Two teaspoons
of baking soda
A glass jar,
flask or a bottle
*30 ml vinegar + 1tsp baking
soda is just fine (KN)
Procedure
Fill the jar with three tablespoons of white
vinegar.
Take out one glove from the box and pour two
tea spoons of baking soda inside. (use funnel)
Wrap the base of the glove over the mouth of
the jar, making sure that no baking soda falls in just yet.
When you are ready, take the attached glove
and put it inside the jar. What happens?
—The Scientific Explanation
When vinegar and baking soda are mixed in a container, they react violently. The balloon (or GLOVE) blows up because a gas called carbon dioxide is created and given off when you mix the baking soda and vinegar.
Research
Questions
·
What do you think will happen when baking
soda and vinegar come in contact (what will be produced)?
·
What do you think will happen to the
balloon attached?
· Why does the balloon stop blowing up (why
does the reaction stop)?
