Made of stainless steel, Chameleon encourages you to drink more water and reduce the use of plastic water bottles. Chameleon, just like its name, is a color-changing stainless steel bottle, the body is covered in thermochromic paint that allows for color changing process when cold liquid is added. It’s unique and cool bottle, designed with one thing in mind, to inspire you to ditch plastic and help save our planet. This project creates a fun hydration bottle that would also track how much you are drinking daily simply from watching that color change. Cold water activates color change, the empty sections of warmer air return the bottle back to white. [Buy It Here]

Chameleon color-changing stainless steel bottle by Root7 can hold up to 600ml liquid. It is sealed with a rubber leak-proof lid to make sure your beverage is safe inside. There’s a handy silicone strap for easy carry, perfect for on-the-go. We strongly suggest that you don’t scrub the surface of the bottle, it can remove layers of that thermochromic paint, simply use warm water and washing liquid to clean. [Buy It Here]
