Candy Science - Dye Job

So here is another candy experiment...Chromatography

We used M & Ms as suggested. You put the candy on drops of water and the result is quite beautiful...


Then add a drop of the colour to a strip of coffee filter (label in pencil with the original colour)

Stand up the filter in water and the water seeps up the filter strip separating out the colours of dye used. (I might recommend a magnifying glass to bring the results close-up (since we didn't use very big drops of colour), or use bigger strips and more colour...

It's fun to see. To help our filters stand up we leaned them on the side of the bowl.
This is a fun one that is easy for the kids to participate, in fact they could do everything. Check out the above link for all the details...very cool ideas.
