Jazz Up Your Morning With the Water-Powered Colour-Changing LED Shower Head Beth Snyder March 23, 2011 I have to admit, when I first saw this, I thought it must be another one of the products for people with too much disposable income. But then I started thinking about it, and I think I want one. Water temperature in my house is unpredictable at best, and I am notoriously NOT awake when I stumble into the shower in the morning. This isn’t just a fun thing to have…it actually tells you how hot the water is before you step under it! Green lights indicate below 90°F, blue covers 91 to 105°F and red is about 107 to 113°F. Anything above that and the shower head will flash red to let you know you’re going to scald yourself if you don’t add some cold to the mix. An internal generator is powered by the flow of the water, so no worries about having to run power and water together. You can pick one up for right around $13.00 US. Source: Oh Gizmo!
