Dancing Raisins!!!!!
Question(s)
Can I use other things besides raisins?
Why and how does it work?
Research
I watched a video on Youtube that explained why the raisins are able to float up and fall back down. Here is the URL address: www.youtube.com/watch?v=R2qGwvFkN_M‎ .

On the website "http://chemistry.about.com" it explained why the baking soda and vinegar react the way they do.

On the website "http://scifun.chem.wisc.edu/homeexpts/dancingraisins.htm" it told me what I needed and how to do the experiment.

On the website "http://www.elmhurst.edu/~chm/demos/danceraisins.html" it told me what I need, the steps to doing the experiment and the chemical reactions.
(I will explain everything in the next slide.)

My
Hypothesis

I
hypothesized
that I wouldn't be able to use anything besides raisins because I thought the bubbles attached themselves to the wrinkles on the raisins and I don't know any other food with wrinkles that is light weight. I also believed that it works because the bubbles carry the raisin to the top and when they pop the raisin falls back down.
Explanation
In the video, it explained that the bubbles are carbon dioxide trying to escape the water and while they're doing that they pull the raisins up and when it reaches the top, it goes into the air so then the raisin falls back down.
In the website "http://chemistry.about.com" it explains that the reaction of baking soda is actually two happening at the same time. The acetic acid (what makes vinegar sour) reacts with sodium bicarbonate (a compound that's in baking soda) to form carbonic acid. Carbonic acid is unstable, and it immediately falls apart into carbon dioxide and water. The bubbles you see from the reaction come from the carbon dioxide trying to escape.
In
conclusion,
I was wrong about having to use raisins, but right about how it works.
In another video (spaghetti one) it showed that you can actually use spaghetti if you don't have raisins and it will still work the same.
Formula
First get all your supplies together in an open space. Once you find an open space, get the glass of water and place it on my table, then
apply
the baking soda and vinegar to the water. After that, get your spoon and stir the water until it is nearly clear and drop the raisins in. Then just
analyze
what happens, it might take a while for the raisins to float up, but sooner or later one of them is going to float up and all the other raisins will do the same
If you don't have baking soda and vinegar you can use soda, but it must be see-through. First you pour the soda into a glass and drop the raisins in.The reaction will still be the same as the one that occurs with the baking soda and vinegar,
Supplies you will need:
baking soda and vinegar or see-through soda
A see-through glass, water bottle or anything you can store water in
raisins (you can use spaghetti but that would be dancing spaghetti not dancing raisins)
an open space
a spoon
Results/
conclusion
I did the experiment at home with baking soda and vinegar. I found out that its a good idea to be close to a sink because you might pour the baking soda and vinegar in to fast and it will fizz up and get you wet. When I did the experiment it did what I expected, the bubbles attached themselves to the raisins allowing them to float up and when it reached the top it popped and the raisin fell back down. I also learned that it takes longer for the spaghetti to float up or maybe my spaghetti is just weird.

All show supplies that are needed
Both show the steps on how its done
shows procedure with images and explains at the same time
Just tells you what steps to do and in what order
Both explain why it works
Both say the steps in order
Explains why and how the raisins are able to float with words but no pictures
