A Smiling Bottle / Bottle

　　When we feed a baby on milk, a common bottle can’t sense temperature and the baby often suffers a lot.
　　I designed a new type of bottle. The pattern on the bottle is made of temperature - sensing materials. As the temperature rises, the color of the pattern turns from no color to green and to red at last, with no color showing too low temperature, red meaning too high temperature. Therefore, only when the temperature of the milk is about 38℃ will the pattern on the bottle show green. Then a baby can enjoy the milk comfortably.
　　Such a new type of the milk bottle will bring safety and convenience to you and your baby.
