What’s in Black Ink?…

To discover what colourful wonders are hidden in an ordinary black felt tip pen: Draw some dots in the centre of a coffee filter or piece of blotting paper. Push a pipe cleaner up through the middle, and extend the other end down into a cup of water. Wait…

…and the colours won’t take long to separate…

We tried other coloured pens too but as you can see the black seems to contain the most colours.
