Here is the challenge that the Science Club was  given today.

 

We cut up the ransom note to test it using chromatography.   To do this we dropped a small amount of water onto the pen to see what would happen.  We noticed that each pen produced a different pattern when the ink spread out in the water.

Next we tested each of the suspects pens by drawing with them and then putting a drop of water on top.

Finally we compared the suspects pens to the ransom note to determine which pen wrote the note.
Two pens were very similar but most of us got it right.
