  1. Rated 5 out of 5

    Found a very practical use for the color changing sheets After one of the pipes under our kitchen sink sprung a slow leak that we didn’t notice until there was a half inch of water sitting in the bottom the cabinet, I went on Amazon in search of something that could alert us sooner if this ever happens again. Luckily I found the color changing sheets which are just perfect for this purpose. Now all we have to do is glance at the bottom of the cabinet each day to see if all is well down there. If white, no issue, if red, water is present!
