Abstract
What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science project you will try to do just that using some interesting materials including a toy/craft product called Space Sand.

Remember that the eluate is the liquid that comes out the bottom of the column, and that each different cup in which the eluate is collected is referred to as a different fraction.
