the pupose is compared to regular water the raisins will sink and the vinegar,bakingsoda with water makes a chemical reaction for the raisins to float.
raisins will float due there carbonarion and the raisins low density level in them.
Raisins sink in water because they are denser. However, the carbon dioxide molecules found in soda float to the top because they want to escape from the liquid. These CO2 molecules (seen as bubles) attatch to the raisins pulling them up to the surface as well. When the CO2 bubles reach the surface, they pop and the raisins begin to sink again.

Raisins dance because when you put a raisin in a lemonade with a small cup of vinegar there are bubbles gonna come up to attach to the raisins then at the top bubbles pop.
take some raisins and drop it into a glass then fill it with clear vinegar and watch it go up then down.
What ever floats in water is not as dense as water and if it has more density then it will sink. Therefore, raisins have less density than water.
The raisins become coated with bubbles of carbon dioxide that leave the carbonated ginger ale. These can cause some raisins to float, or to pop up and down along the bottom of the glass. If the ginger ale goes "flat" then the raisins will sink to the bottom and stay there.
salt water because the raisins the salt expands the raisins
it would absorb the water into the raisins to equal out the concentration within the water and the raisins.
the purpose of the dancing raisins project is showing that the carbonation of the soda can float the raisins up in tiny bubbles and make them dance
