This is a fun little experiment to do to find out what color inks make up your black (non permanent) marker. You’ll need a black non permanent marker and coffee filters. After doing the experiment we actually found more colors came out on the non bleached coffee filters – not sure if that has something to do with the thickness or the fact that they white ones are bleached.
Draw a line about an inch above the bottom (we cut out circles of our filters so they would lay better) or a dot in the middle.
For the circles with lines place them in a SMALL amount of water – too much water and it will rise too quickly, better to start off with too little.
For the filters with dots place them on a plate and drip a few drops of water onto the dot.
Watch as colors “magically” appear!
Try it with different markers and different filters to see if the colors are different! Let us know what you find.

We used to do this when I worked at a children's museum and you can actually do it with permanent markers, too! Instead of using water, you use rubbing alcohol.
