A report: MEDAL is an essential part of marathon and the most
important AWARD who attract more and more RUNNERS!!!
Thermochromism is a property of substances to change color due to different temperature. We applied this material to our medals, the face of the pig's color will change when we pour some hot water or use our fingers to rub it's face. How Amazing!!! See the video show on our Instagram!
