Have you ever looked at a drop of water under a microscope?  Not me either. Well 3M is giving away free test kits so you can check what is in the water you drink and use everyday.
In drop down box at end of form–reason for contact–mark order free test kit.  You will also need to put something in the comments box or form will not go through. I just put thank you.
