For this experiement you will need a cake pan and an old vase
from your moms kitchen cupboard. The case pan is used to
catch the awesomeness you are about it make. You will need a TBSP to use to measure out your baking soda with.
Put about 4 TBSP of baking soda in your vase. There is no real need
to measure out exactly four TBSP of baking soda.
Keeping your TBSP will actually make your explosion bigger and better.
Oh and don't forget to make sure you are using baking soda and not
baking powder. Next pick your favorite color of food coloring. I choose
green and put about 6-8 drops in my vase, I also used glitter to give
to explosion a little sparkle. I chose another one of my favorite colors and adding another heaping TBSP to my vase.
Now here comes the fun part. Use your white vinegar and one measuring cup
Make sure you have your mom and dad help you with
this part because it can get pretty messy and pretty stinky.
Fill up your measuring cup with your vinegar and pour it into the vase.
And let the magic begin. This explosion happens because the chemical reaction.
The baking soda is a base while the vinegar is an acid.
When mixed together they become unstable and instantly break apart
into carbon dioxide and water, this creates all the fizzing. After your explosion fizzles out make sure to help
your mom and dad clean up your mess.

For this experiment you will need to place your
mason jar on a flat surface like your kitchen table or your counter.
Next take your soda and pour it into your jar up to about where
my finger is at. 3/4's of the way. Then take your box of raisins
open them and pour about 6-8 into your soda.
Now let me explain how and why your raisins are dancing.
The raisins are more dense than the soda so at first they sink
to the bottom of the jar. The soda releases the carbon dioxide bubbles.
When these bubbles stick to the raisins, they lift because of the increase in
boyancy. When the raisins reach the surface, the bubbles pop and the carbon
dioxide escapes into the air. This causes the raisins to lose boyancy
and sink. The rising and sinking continues until the soda
loses carbon dioxide and goes flat.
Now we will do the same experiment we just did but this
time we will just use plain tap water. Fill your jar up at 3/4
the way with your tap water, just like you did with your soda, next
take your raisins and pour about 6-8 into the water and watch.
The raisins do not dance because the water does not contain
carbon dioxide like the soda did.
