This Chinese phone case has a cool little effect to it – it changes its colour when affected by high temperature. Normally, the case is red, but when touched by something of around 35 Celcius degrees it temporarily changes to yellow. The above picture, well, pictures this very well – holding the phone in your hand leaves cool, yellow marks on the case, making it look like some kind of postmodernistic painting worth at least 500 thousand dollars. Hot summer is probably the best time to play around with it.

For a Chinese gadget, case is pretty well made – it is said to be durable, to look a bit like synthetic weather and to fit well over the phone. If you want to get one for yourself, go check out an online store with Chinese products (for example AliExpress) and look for so called ” thermal cases”.
