Creating your own homemade case design for your iPhone is a great DIY project. This tutorial teaches you how to make an incredibly geeky case that is heat sensitive and able to reveal markings showing off your finger prints.
Barry Neeson shares this extremely cool case design and how you can up-cycle your old smartphone case into a fun science experiment. The project begins with an unused phone case that is then covered in a bright color thermochormic pigment that is heat sensitive. The pigment is mixed in with a white acrylic paint and then applied in layers onto the smartphone case. Once the case is dry you can seal it with a lacquer and watch as with every touch the bright colored case turns white from the heat in your hands.
