Wondering if your water is full of cat urine or mind-altering fluoride? Place a single drop of water from any source onto the device then it will display either a happy face or a sad face depending on the quality of water. Let's hope to see more emoticons in futures releases of this device. For example slashy faces for so-so water and a crying face for "yeah this water is so bad you will be developing a kidney stone soon." This is available for $29.
